Looking to shoot an AR-platform rifle out past 500 yards? Then you should read two articles by AR guru Glen Zediker. Author of The New Competitive AR-15 and The Competitive AR15 Builders Guide, Zediker is an expert when it comes to AR-platform rifles. Glen believes ARs have excellent long-range capability, provided they are built to high standards, with good barrels. Glen says: “a properly configured AR-15 is easily capable of good performance at 500+ yards. Good performance means it can hit a 1-foot-square target all the time. Competitive shooters can cut that standard in nearly half (the X-Ring on an MR1 600-yard NRA High Power Rifle target is 6 inches, and high X-counts are commonplace among more skilled shooters).”
Published in the Cheaper than Dirt Shooter’s Log, Zediker’s pair of articles cover the history and upgrading of the AR-15. Part One reviews the AR’s development as an accurate firearm, tracing its evolution from a Vietnam-era combat weapon to what is now a favored target rifle of High Power competitors. READ PART ONE.
Part Two discusses the specifics that make an AR accurate at 500 yards and beyond. Zediker talks about barrel configuration (profile and twist rate), bullet selection, floating handguards, and proper mounting of optics or iron sights. READ PART TWO.
Barrel Twist Rate
To stabilize anything longer than a 68- or 69-grain bullet, the barrel twist rate must be — at minimum– 1-in-8. Twist rates reflect how far the bullet travels along the lands or rifling to make one complete revolution. So, 1-in-8 (or 1-8, 1:8) means “one turn in eight inches.” I think it’s better to go a little faster in twist. There is nothing wrong with a 1:7 twist. The 90-grain bullets require a 1:6.5, and that is getting on the quick side. If you want to shoot Sierra 77s or equivalent, and certainly anything longer, 1:8 is necessary. By the way, it is bullet length, not weight, which constitutes the necessary twist rate to launch a stable bullet.
Correct optical sight positioning can be a challenge. With a flattop upper, I need a good inch additional forward extension at the muzzle side of the upper for the sight mount bases to avoid holding my head “back” to get the optimal view through the scope. A longer rail piece is necessary for my builds as a result.
Buttstock Length and Adjustment
An adjustable buttstock is valuable, and even more valuable if it’s well-designed. Mostly, a standard stock is too short, and the cheek area sits too low. Adding length helps a lot by itself. There are assemblies that replace the standard buttplate to allow for length and, usually, height and rotation adjustments for the buttpad. An elevation-adjustable cheekpiece is a big help to attain a solid position.

Does your Black Rifle have a sloppy upper/lower fit? That can be annoying; what’s more, loose fit can limit accuracy potential. Here’s a clever solution for poor-fitting AR-15 and AR-10 upper and lower receivers. The new JP MicroFit takedown pins can improve even the sloppiest ARs, providing a rock-solid upper/lower receiver fit.
MicroFit pins come in three sizes and two types: standard (“mean”), oversized, and undersized, with types for both front and rear of the receivers. The mean pins match standard takedown pin sizes while the over- and under-sized vary by slightly more than .001″ (+/-) from the standard diameter. NOTE: Although most poor-fitting receivers are loose, some are too tight. Very tight receivers, such as post-Cerakote, can be remedied with the undersized pins.
Shown is JP Enterprises’ PSC-12™ upper assembly with LRP-07™ lower assembly.
“An AR with a loose upper/lower receiver… will not reach its accuracy potential. That was the goal with our original JP Tension Pin, but MicroFit™ pins provide the same result without tool-assisted takedown. The MicroFit pins require no modification to the receiver. They simply replace your current pins”, stated JP Enterprises founder John Paul.
JP’s MicroFit pins feature a polished black finish with a hard, durable QPQ coating. This provides smooth insertion/removal plus excellent corrosion resistance. All pins feature a two-faceted punch or bullet capturing recess. This allows the user to apply force to the pins safely without risking scratching the receiver. JP’s MicroFit pins are sold as both as individual pins and as replacement sets.

The Precision Rifle Series (PRS) for tactical bolt guns has become hugely popular. Capitalizing on that success, the PRS has approved a new Gas Gun series for semi-auto rifles such as AR15s and AR10s. Since the launch of the PRS a few seasons back, Gas Gun shooters have wanted to play. Recognizing the interest among semi-auto shooters, the PRS ran two “prototype” Gas Gun matches last year.
PRS Director Shawn Wiseman Explains New Gas Gun Series in this Video:
Based on positive feedback from the 2016 test matches, PRS founders approved a full 2017 Gas Gun series which kicks off this week. The 2017 PRS Gas Gun Series opener will be held February 17-19, 2017 at the CORE Shooting Solutions range in Baker, Florida. Here’s a video showing CORE’s facility:
For the new PRS Gas Gun Series, rules and scoring procedures needed to be developed. Accordingly, a committee of top PRS shooters, Multi-Gun shooters, and Match Directors was assembled to develop the PRS Gas Gun Series Rule Book. Highlights of the Rules are listed below.
SSUSA: What will be the format of the 2017 PRS Gas Gun Series matches?
Wiseman: The matches will be a two day format with 8 to 10 stages per day. No more than 50 percent of the stages can be unlimited round count and 25 percent of the targets must be 2 MOA or smaller. The scoring will be overall time plus penalties with the winner being the shooter with the fastest time including all penalties. There are three Divisions; Tactical Light for 5.56x45mm NATO/.223 Rem. rifles, Tactical Heavy for 7.62x51mm NATO/.308 Win., and Open for everything else up to .30 cal. The maximum distance will be 800 yards.
SSUSA: What guns do you expect to be popular?
Wiseman: In the Open Division, I expect to see a lot of 6.5 Creedmoors for two main reasons; it’s an inherently accurate cartridge and Hornady makes great ammo for the folks that aren’t into reloading. I think the Tactical Light Division will probably be the most popular. It is hard to say specifically what rifles will be the most popular but there are a few AR companies that are known for the accuracy. Armalite, GA Precision, LaRue and Seekins will all be very popular rifles in this Series. I think we will continue to see high-end optics with 5 to 6X zoom range on the rifles. Bushnell, Kahles, Leupold, Nightforce and Vortex will continue to be the most popular.
Scoring and Penalties
The Gas Gun Series utilizes a time plus penalty-based scoring system for all match scoring. This means the score is the shooter’s total combined time on all stages plus any penalties accrued.
Penalties are as follows:
30 seconds for any rifle targets not engaged or neutralized.
15 seconds for any pistol targets not engaged or neutralized.
15 seconds for hitting a “No Shoot” target.
No more than 50% of the stages at a match can utilize an unlimited round count. At least 25% of the targets in Gas Gun Series match must be 2 MOA or smaller. Maximum distance is 800 yards.
Open Division: The Open Division rifles will not exceed a caliber of .30 or a velocity of 3,200 fps. A match DQ will result any rounds over the speed limit of 3,200 fps (+/- 32 fps for environmental factors and equipment discrepancies). Match Officials may request at any point during a match that a competitor fire their rifle through chronograph. If the bullet exceeds the 3,200 fps speed limit, the shooter will receive an automatic match DQ.
Tactical Light Division: Intended to allow competitors the opportunity tocompete using traditional military and law enforcement caliber. This promotes Active Duty military and law enforcement competitors use of their Service and Department-issued rifles. Tactical Light Division rifles are restricted to 5.56 NATO/.223 Remington calibers only. Bullet weight cannot exceed 77 grains and muzzle velocity cannot exceed 3,000 fps.
Tactical Heavy Division: Intended to allow competitors the opportunity to compete using traditional military and law enforcement caliber. This promotes Active Duty military and law enforcement competitors use of their Service and Department issued rifles. Tactical Heavy Division rifles are restricted to 7.62 NATO/.308 Winchester calibers only. Bullet weight cannot exceed 178 grains and muzzle velocity cannot exceed 2,800 fps. No modified wildcat rounds permitted to shoot in the Tactical Divisions Anyone discovered violating this rule will receive an automatic Match DQ. Tactical Division shooters will shoot the exact same COF as Open Division shooters.

This shocking photo of destroyed AR-15 bits and pieces was posted on Facebook by William Walter, a firearms instructor. William said this was “The worst AR-15 blow-up I have ever seen. Has anyone else seen one this bad?” It is indeed catastrophic. Seeing the above image, our friend Grant Ubl wrote: “that is most definitely THE most FUBAR’d AR15 that I have ever seen”.
Luckily the shooter sustained only minor injuries — nothing worse than a broken finger tip. But his AR-15 is certainly toast. The lower was polymer. Note the past tense. According to Walter: “It was a polymer lower and polymer magazine. Pieces of both were distributed up to 25 feet from the bench he was firing from.”
The cause of the Kaboom is somewhat mysterious. The Kaboom occurred on the 4th round fired — the first three went OK, and there is NO evidence of a squib load (i.e. no bulge in barrel). This was definitely NOT a .300 BLK round in a .223 Rem Chamber. William Walter suspects that pistol powder may be involved, but that has not been confirmed.
First thing I suspected was bore obstruction, but there wasn’t any sign of it. The case head literally atomized…you can see the brass residue on the parts. The bolt was split in two also. This was number four fired during load testing. The previous three were fine…no high pressure signs on the primer. — William Walter
One Facebook poster noted: “We had one similar here in PA about 14 years ago. The guy used Winchester 231 instead of Winchester 748 and ended up with a pile of parts very similar looking. The rifle went Kaboom on his first sighter in offhand and no one was injured surprisingly. The carrier looked like someone cut it down the middle with a torch very similarly to this picture. It also cut the bottom of the carrier and all three pieces look like a peeled banana.”
Walter stated that here: “[The shooter] had fired four rounds of the same load. He was shooting Win 748…24 grains with a 77 Sierra. I will reserve my theory until after we discuss as to not steer the conversation.
On reading that, Dennis Santiago posted: “Did you mean WW 748? That’s on the fast side powder for a .223 meant for lighter bullets. 24 grains with a long bullet like a Sierra 77 would be way too much.”
Walter noted that there was a possibility of some pistol powder getting into the catridge that detonated: “[The shooter] said he does load pistol and this was first time loading rifle. He said he used his 650 powder measure, but also a funnel and trickler.” Considering that, one poster suggested that maybe pistol powder was still left in the bottom of the powder measure.
It will be interesting to determine what exactly happened here. The remaining rounds from the same loading session will be pulled down and analyzed. A discussion of this incident appears on the Precision Shooting Journal Facebook Page.
Question to our readers: What do you think was the probable cause of this catastrophic Kaboom?

Ever wondered how the parts inside an AR15 work together? Just exactly how does the reciprocating bolt carrier feed rounds from the magazine? How do the elements in the trigger group work and reset after each shot? How does the gas system bleed gas from the barrel and operate the bolt carrier? These and other questions are answered in this eye-opening video from 45Snipers. Using “cutaway” 3D computer animation, this 5-minute video shows all features of an AR15 inside and out. This fascinating firearms animation allows the viewer to look inside the upper and lower receivers, into the bolt carrier, chamber, barrel, and magazine.
This video starts off slow and has annoying background music, but it is well worth watching if you own or shoot any AR-platform rifle. It illustrates all the key operations during the charging, loading, firing, and ejection processes. The cutaway animation shows how rounds are stripped from the magazine and then chambered. It then shows how every part of the trigger group works, and how the firing pin strikes the primer. You can even watch the bullet move down the barrel before the empty shell casing is removed from the chamber and tossed out the ejection port. Here are sample frames from the video:

SHOT Show is a cornucopia of products, with everything gun-related under the sun on display. The SHOW features a vast array of items for hand-loaders. Here are some of the most notable reloading and ammunition products we found at SHOT Show, Wednesday, January 18th.
Alliant Reloder 16 — Great Powder — Accurate and Temp-Stable
If you like Hodgdon H4350, you should like Alliant’s Reloder 16 powder. First revealed at SHOT Show 2016, the impressive Reloder 16 is now widely available at vendors nationwide. This advanced-formulation powder is extremely temp stable. We confirmed that during hot weather testing sessions last summer. In addition, in mid-sized match cartridges such as the 6XC, 6mm Creedmoor, 6.5×47 Lapua, and 6.5 Creedmoor this powder has shown impressive accuracy. No hype — our Forum guys who’ve used Reloder 16 have told us this stuff can deliver match-winning results. This is definitely a viable rival to H4350. We recommend you buy a pound and test it.
Reloder 16 is NOT just a slower version of Alliant’s double-based Reloder 15 (which words great in the 6mmBR and Dasher cartridges). Reloder 16 is a completely new formulation, produced in Sweden by Bofors for Alliant. Reloder 16 utilizes TZ technology, which resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures. Based on the test results we’ve seen, if you are using H4350 or IMR 4451 currently, you should definitely give Reloder 16 a try. The powder also boasts excellent lot-to-lot consistency and contains a proprietary de-coppering additive.
Lapua 6.5 Creedmoor Brass
The 6.5 Creedmoor has been “all the rage” at SHOT Show 2017. This cartridge, a proven winner in PRS competition, is riding a huge wave of popularity right now. There are many great factory rifles now offered with this chambering. And now we have superb Lapua 6.5 Creedmoor brass. You read that right Lapua is now producing ultra-premium 6.5 Creedmoor brass that will “raise the bar” for this cartridge. Lapua’s new brass features a small primer pocket and small flash hole (just like Lapua’s superb .220 Russian, 6mmBR, and 6.5×47 Lapua brass). This small primer pocket design can deliver longer brass life, and (potentially) enhanced velocities. We predict serious 6.5 Creedmoor shooters will be switching to this brass as soon as it becomes available later this year. NOTE: The new Lapua 6.5 Creedmoor brass can also be easily necked down for the 6mm Creedmoor.
New RCBS ChargeMaster Lite
RCBS unveiled a new, more affordable electronic powder scale/dispenser system. Called the ChargeMaster Lite, this new-for-2017 unit has some features we really like. The touch screen is easy to use and the power tray cover slips off easily — no more hinges to fight. Most importantly the CM lite has a redesigned, fluted dispensing tube which delivers powder kernels is a smooth flow with no clumps. The RCBS Rep told us “No more McDonald’s straw required”. We tested the unit and it does seem like the newly-designed dispensing tube is better. In fact, this new design will be adapted to the next generation of larger ChargeMasters.
Here is the RCBS Press Release: “The new RCBS ChargeMaster Lite packs unparalleled powder-measuring accuracy in a compact package. The one-piece unit features an LCD touchscreen display that ensures accurate data input. The hopper holds nearly a pound of smokeless powder, and can dispense anywhere between 2 to 300 grains with a +/-0.1-grain accuracy. The ChargeMaster Lite is an effective, accurate powder-measuring tool. Featuring 120/240 switching power supply, the ChargeMaster Lite is EU/UK/AUS compliant, includes a cleaning brush and two calibration/check weights and has an MSRP of $299.99.”
22 Nosler Brass and Ammunition
Here’s a new higher-capacity cartridge designed for folks who want to step up from the .223 Remington in their AR-platform rifle. Nosler has created a new SAMMI-spec cartridge which is similar to a 6.8 SPC necked down to .224 caliber. Nosler says the .22 Nosler cartridge will deliver significantly more velocity* than a .223 Remington, when shooting the same weight/type of bullet. For varminters using AR-style rifles, that’s a significant performance gain. We hope to test the 22 Nosler this spring in the varmint fields. This little round should definitely out-perform the standard .223 Rem cartridge while still operating from a standard AR platform, using the same bolt carrier group but with different, 6.8 SPC magazines.
Nosler explains: “Retrofitting a standard AR-15 chambered in .223 Rem / 5.56 NATO to a 22 Nosler is simple. All that is required is a simple barrel swap to the new 22 Nosler chambering, run 6.8 Remington SPC magazines instead of 5.56 magazines and the swap out is complete. Approaching 22-250 velocities in a significantly smaller package, the 22 Nosler® yields nearly 25% more capacity than the 223 Rem/ 5.56 NATO making the round capable of pushing a 55gr Nosler Ballistic Tip bullet at 3,350 fps out of an AR-15 fitted with an 18″ barrel and a 77gr Custom Competition® bullet at 2,950 fps.”
*When Nosler’s listed 22 Nosler velocities for 55gr and 77gr bullets are compared with .223 Rem maximum loads from Hodgdon load manuals, it looks like the speed gains with the 22 Nosler are 250-300 FPS, or about ten percent.

We call them “black rifles”, but that shouldn’t refer to all the carbon and gunk on the inside. AR-platform rifles can be maintenance-intensive beasts. But some AR owners make the situation worse by not regularly cleaning important small parts, or by using too much oily/greasy lubricants in the wrong places. A properly maintained and lubricated AR15 can shoot hundreds of rounds (between cleanings) without a problem. If you learn where (and where not) to apply lubricant, you’ll find that your AR will run more reliably and the task of cleaning the bolt and bolt carrier will be less of a burden.
Here is a good video that explains AR-15 Cleaning and Maintenance. In this 30-minute NSSF video, Gunsite Academy instructor and gunsmith Cory Trapp discusses the proper way to clean and maintain the AR-15 carbine. Very knowledgeable, Trapp provides rock-solid advice for AR owners. Along with cleaning producedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.

Rimfire shooting is one of the fastest-growing firearm sports in the USA. One of the most important rimfire events of 2016 was the NSSF Rimfire Challenge World Championship held October 14-16 at the Cavern Cove rimfire facility in Woodville, Alabama (near Huntsville). Hundreds of shooters of all ages attended this fun event.
Families Enjoy Rimfire Fun at the NSSF Rimfire Challenge
At the 2016 NSSF Rimfire Challenge Championship in Alabama, Smith & Wesson was on hand with demo rifles and pistols. See the action in the S&W-produced video above. Competitive shooting is one activity in which entire families, both oldsters and youngsters, can come together in a supervised setting to enjoy the spirit and camaraderie of competition. At the October event, attendees were able to try out the Smith & Wesson® SW22 Victory pistol and the M&P 15-22 rifle.
In this video, our friend Julie Golob explains the features of Smith & Wesson’s AR-style M&P 15-22 rifle. We’ve shot the semi-auto M&P 15-22 and it’is a ton of fun. It offers familiar AR15-type ergonomics and balance, with excellent reliability, and the inherently low recoil of the .22 LR rimfire cartridge. All that combines for affordable fun for the whole family.

Each Wednesday, the U.S. Army Marksmanship Unit (USAMU) publishes a reloading “how-to” article on the USAMU Facebook page. In this article, the USAMU’s reloading gurus address a question frequently asked by prospective handloaders: “Should I buy a single-stage press, or a progressive?” The USAMU says the best answer is Solomon-esque in both its wisdom and simplicity: “Get BOTH!” However, there is definitely more to the issue, as the USAMU explains below.
Progressive Press Safety Considerationsby USAMU Staff
Many are the beginning handloaders who have asked a friend about their “setting up” a progressive press for them. The idea is that the newbie could then just feed in components and crank out buckets of practice ammo without needing to really learn much about handloading. Tempting though this might be, that’s simply not how it works. Such an approach might be ok if there were never a malfunction with either press or operator, but that’s unrealistic. Our hypothetical newbie would then lack the knowledge to problem-solve most situations.
This video from the U.S. Army Marksmanship Unit focuses on two key fundamentals of marksmanship: 1) Sight Alignment; and 2) Trigger Squeeze. This video can assist any Service Rifle or metallic sights shooter. The USAMU instructor explains: “You’ve probably heard a lot about fundamentals — Breathe, Relax, Aim, Squeeze… Well that gives a shooter a lot to think about. Here we teach two main firing tasks: 1) align the sights, and 2) squeeze the trigger without moving the rifle. This allows the shooter a much more simplified format.”
The following tips are transcribed from the video:
Task One: Sight Alignment
Sight alignment is the process of putting the tip of the front sight post, the rear aperture, and the shooter’s eyeball all on the same plane. It’s very important to maintain the tip of the front sight post centered in the rear aperture. Just .002″ of deviation can cause a miss at 300 meters. Allow your eye to do its job. While firing, the focus should remain on the tip of the front sight.
Task Two: Trigger Control
Your second firing task is [to] fire the rifle without moving it. This is done through proper trigger control. You’ve probably heard a lot of words about trigger control — “surprise break”, “snatch”, “pull”, “squeeze”… well we teach one thing here: “smooth”. No matter the speed at which I engage the trigger, it’s always going to be smooth. Imagine trying to pull the trigger straight through the rear of the buttstock, holding it to the rear while the gun recoils. It’s important to constantly engage the trigger, never letting your trigger finger disengage from the trigger while firing. This is achieved through natural trigger finger placement.

One of our Forum members asked us the question: “Does anybody make a good range box with cradles for cleaning at the bench?” The answer is yes — the MTM model RBMC Range Box offers slide-in plastic cradles that provide a reasonably sturdy platform for a quick clean when you’re done shooting. The RBMC box also offers plenty of storage for jags, brushes, solvents, ammo boxes and other miscellaneous gear you need for the range.
Among the many range boxes available, the MTM model RBMC Range Box leads the pack in terms of versatility. It is rugged, it has plenty of storage space, and it doubles as a handy cleaning station. This Editor has used the MTM Range Box to clean rifles and as a “range expedient” rifle holder when adjusting scopes and tensioning action screws. It’s a good product that does the job and stands up to rough handling.
Fitted Cleaning Cradles
The key feature setting MTM’s RBMC apart from most range boxes is the rubber-coated cradle system. Wide enough to fit a 3″-wide fore-arm, the cradles slide into vertical slots on either end of the box. This allows your range box to serve as a maintenance station. The RBMC is really pretty stable in this role, and the cradles won’t mark your stock. The cradles even feature slots on each side to hold your cleaning rods. The MTM Range Box is secure enough to stay in place when you’re brushing the barrel. However, if you’re working on a carpeted bench top, keep one hand on the box when running a cleaning rod through the bore, just to ensure the box doesn’t slide.
Versatile Upper Tray with Dividers
The MTM Range Box has two major components — the box base (with cradles), and a large upper tray with hinged top and carry handle. This large upper tray clamps securely to the bottom unit for transport. The top tray has a long section that holds cleaning rod guides, long brushes, grease syringes and the like. There are two, clear-plastic fitted divider trays. These will hold your patches and jags, plus comparators, ring wrenches, and other small tools.
What Might Be Improved
Though we really like the MTM Range Box, it’s not perfect. First, we wish the box was a bit deeper, to have added carrying capacity. The dimensions of the MTM Range Box are: 25″ long x 11.5″ wide x 8.75″ high. We’d like to see it 12″ high/deep to allow larger solvent bottles to stand upright and to provide more space to carry tools and shooting muffs. However, it is deep enough to hold the large 100-round MTM cartridge boxes that are popular with many shooters (see photo at right).
While we like the twin clear plastic dividers that fit into the removable top-tray, but we wish the dividers had individual hinged tops. This would keep small items more secure.
At the request of our readers, we provide select “Deals of the Week”. Every Monday morning we offer our Bargain selections. Here are some of the best deals on firearms, hardware, reloading components, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.
The RCBS Rock Chucker remains a classic — a big, strong, versatile press that can handle most reloading chores with ease. And now you can get a genuine Rock Chucker Supreme for $126.99 — a very good deal. The Rock Chucker offers plenty of leverage for case-sizing and the “O” is tall enough for long cartridges. The Rock Chucker has a very strong base and should last a lifetime. We’re not fans of the Rock Chucker’s priming system but most serious reloaders use a separate priming tool.
2. Midsouth — 17 HMR V-Max Ammo, $10.45 for 50 rds
Need 17 HMR ammo for your varmint safaris? Then grab this Hornady V-Max ammo while you can at $10.45 for a 50-round box. This is a great price. Other vendors are selling the same Hornady ammo for as much as $15.00 per box. We’ve used this ammo and it was very accurate out of both semi-auto (Savage A17) and bolt-action (CZ 455) 17 HMR rifles.
3. Aero Precision — Upper and Lower Stripped Receivers, $189.99
If you want to build your own AR for varminting, self-defense, or competition, here is a great value for the basics. Right now Aero Precision is offering a combo set of AR15 Stripped Upper Receiver PLUS AR15 Gen 2 Stripped Lower Receiver all for $189.99 with free shipping. The upper and lower are both machined from from 7075-T6 aluminum forgings and have a tough, Cerakote finish. This upper/lower set features 0.250″ takedown pin holes and M4-style feedramps. Both upper and lower take standard AR15 components so you can choose from a wide selection of trigger groups.
The Jewell trigger is still probably the most commonly-used trigger in benchrest competition. Right now at Grafs.com you can get a Remington 700-compatible Jewell benchrest trigger for $179.99 — that’s $20.00 of the regular price. This single-stage trigger adjusts from 1 ounce to 3 ounces pull-weight, and has a crisp, precise release. This will fit Rem 700 actions as well as Rem-compatible custom actions. This trigger does NOT have a safety and it is NOT recommended for hunting applications. (Sale tip from EdLongrange.)
5. Cabelas — Howa 1500 Mini-Action in .223 Rem, $349.99
Here’s a good deal on a great little rifle. Right now at Cabela’s you can get the Howa 1500 Mini-Action in .223 Rem for just $349.99. That’s a bargain — other vendors are charging $500.00 or more for this rifle. The Howa 1500 Mini Action is nearly an inch shorter than a Rem 700 short action, making for a nice, compact carry-around varminter. Your Editor checked out the Howa Mini Action Rifle at SHOT Show. The bolt opens and closes VERY smoothly (way better than most mass-produced bolt guns). The two-stage HACT trigger is excellent — it’s plenty light, with a crisp release and no annoying spring-loaded blade in the middle.
If you shoot long range, you need a scope level. This Discovery scope level is fully CNC-machined to close tolerances for a good fit. It is available with three inner diameters to fit scopes with 1″, 30mm, or 34mm main tubes. The 1″ version is just $11.99 while the 30mm model is $13.95 and the large 34mm version is $15.95. You could easily pay $35.00 or more for a 30mm scope level. Purchasers have praised this product: 89% of verified buyers rated this five stars.
7. Eabco.com — Pillar-Bedded Laminated Stock for Savage
For a Savage-based general purpose rifle, this Laminated Thumbhole Savage Stock is a good choice, and a fine value at just $175.00 including installed pillars. (Most bargain-priced laminated stocks do NOT include pillars). This stock fits Savage actions with detachable magazines. There are four color options: Camo laminate (shown in photo), Brown Laminate, Gray Laminate, and walnut color.

Many of our readers have never had a chance to shoot much past 600 yards. How far away does a 1000-yard+ target really seem to the naked eye? Well this short video answers that question. Gorilla Ammo, the video’s producers, used a camera-carrying aerial drone to fly downrange from the firing line all the way out to 1122 yards (and back again). Watch the drone footage at 0:00-0:07 and especially 0:48-1:03. The “bird’s-eye view” really gives you a sense of the distance. The “fly-back” at 0:48-1:03 time-mark is what makes this video worth watching.
The video features prone shooting at steel targets placed at 750 and 1122 yards. We do apologize for the lame, “oh so serious” voice-over which attempts to make this rather ordinary range session seem like some kind of life-changing experience. (Frankly, you may just want to turn the sound off — it’s that annoying.) It’s really not that big a deal to hit steel at 750 yards with a quality AR-15, chambered in .223 Rem, shooting Sierra 77 grain MatchKings.
Hitting Steel at 1122 Yards with 2540 FPS Ammo Can Be Challenging
The 1122-yard hits are a bit more impressive. Gorilla Ammo lists a relatively sedate 2540 fps Muzzle Velocity for its .223 Rem 77gr SMK ammunition. According to JBM Ballistics, at 1125 yards, that 2540 fps load has 68.3 MOA of drop from a 100-yard zero (firing at sea level and 80° F ambient). Morever the bullet goes trans-sonic around 750 yards (losing stability) and is traveling just 933 fps at impact. And the wind’s the killer — at 1125 yards, with this bullet/load, a mere 2 mph, full-value wind change can move the Point of Impact over three feet!

This summer, our friend Dennis Santiago made his first-ever pilgrimage to Camp Perry, Ohio to compete in the National Matches. He recounts his experience in a fascinating, informative, and often humorous story on his Dennis Talks Guns Blog. When you have a few moments to spare, you should definitely read Santiago’s account of his First Time at Camp Perry. This is much, much more than a match report. Dennis gives insights into the human side of the experience — and the little things that make Camp Perry so special. CLICK HERE to Read Full Camp Perry Story.
Dennis competed in a number of events during his two-week stay. Shooting “classic” service rifle and his new scoped, “modern AR” service rifle Dennis competed solo (in Presidents 100 and NTI matches among others) and also as a member of the California Adult Team in the 4-man NTT match.
Santiago’s First Time at Camp Perry report is a “must-read” for anyone contemplating a Camp Perry visit. Here are some highlights — but honestly folks, do read the entire story — it’s well worth it.
First Time at Camp Perry, by Dennis Santiago
Perry Ain’t Like Home
Iron Sights and “Perry-Vision”
This range is kicking me hard. I tell people about how hard I was pushing my eye into my aperture. They smile that “welcome to Camp Perry” smile again. They ask what sights I’m shooting on my A2 and I tell them I’ve got an 0.050″ front and 0.038″ rear to maximize depth of field. They smile more broadly and tell me my problem is that I’m from the Western provinces where the sun is bright and the ground is devoid of flora. Lots of light. It’s green here and we have clouds I’m told. Not nearly the same ambient lighting. You have the wrong sights my son. Where the green grass grows you want a big fat 0.072″ front the size of an aircraft carrier deck and a huge 0.046″ hole in the morning and maybe close it down to an 0.042″ rear aperture later if the sun comes out. But that desert glare sight system of yours will lose you about 5-8 points in these parts. Well there you go. Learn something every day.
Baptism at Camp Perry
One’s first visit to Camp Perry is a series of baptismal rites. I shall now enumerate them…
Walk the Base. Do not drive around. Get used to walking. Walk from your hut to everything. Walk to the administration buildings. Walk to the ranges. Walk to commercial row. Walk to the CMP North Store. Walk to the CMP or Army trailer to have the triggers of your rifles(s) weighed. Walk. This is your primary mode of transportation while on base for the next couple of weeks.
Go Shopping. It’s called Commercial Row. It is the best shopping mall for competitive shooters ever. The sale prices here are Black Friday quality. You stock up on supplies. You can buy elusive powders in quantity with the same lot number. Same with bullets and primers. Everything you need to keep making your pet loads. Oddly, not cases. This is a service rifle tournament. Pretty much everyone is using LC or WCC cases. I stocked up. Then I began politely watching my expected cubic feet and gross weight capacity for the drive home as other people asked if I could take stuff back for them instead of shipping their loot.
Learn about the Perils of Perry. One, evacuate the range. It rains at Camp Perry. Sometimes that rain comes with lightning. When that happens range controls issues an evacuation order. Depending on where you are and how much time you have, you either grab your stuff and make for a sheltered structure or leave your stuff under whatever rain cover you have and leave it there until the storm cell passes. This happened on squadded practice day. There was no squadded practice. There was learning to make a better rain cover for the next two weeks because it’d probably happened again. I was particularly proud of my final design which involved a very large tarp and many bungee cords. Modern art to be sure. I received many compliments.
Peril Two — Cease fire, boat in the impact area. One has not truly been to Camp Perry until your shooting string is put on hold while range control sends someone out to tell an errant yacht or jet ski that it’s not a good idea to go into that area with all the buoys with the signs on them that say, Danger. Live Fire. Keep Out.
I brought two rifles with me to Camp Perry. The first was my iron sights-configured AR-15. Being my very first trip to the Nationals, I wanted to check off a bucket list item to shoot irons at a National Match. The gun has a Geiselle trigger and an upper I assembled from White Oak Armament parts. The barrel is a Krieger that had 3,800 rounds arriving at Perry. The sights are pinned 1/4×1/4s. I run Sierra 77gr SMKs short line and 80gr SMKs seated .015″ off the lands Long Line with it.
The other rifle I brought was for NRA week. It’s a 2016 Rule Service Rifle, Optic. It has a collapsible UBR stock and a Geiselle Mk VII quad rail. The barrel is an older DPMS .223 that was cryo-treated back in the day. Round count on arrival at Nationals was around 1,800. Same ammunition combination [as the iron sights rifle]. The chamber on this barrel has a shorter throat so I brought a Lee Hand Press with an RCBS competition seater die to set the 80gr SMKs back to proper jump for NRA week. The sighting system for this gun was one of the very new Nightforce 4.5X Competition SR’s with the CMP R223 reticle. Parallax is set to 200 yards. It’s mounted using Nightforce’s superbly engineered AR-15 service rifle Unimount.

Coaching — When It All Comes Together, at Last
I coached one of the California teams in the NTIT Rattle Battle match. This was the day I finally began to be comfortable at Camp Perry. Walking up and down the field, first as a verifier and then as a coach, I felt back in the game. At team matches you get to confer with your teammates comparing wind calls and observing the effects of their calls as the shooting members of their squads send rounds downrange. You watch the traces of bullets arcing in the air going left or right of the bull’s center depending whether or not the call was right. This process was cathartic. I began to remember that I really can read a range once I get the hang of it.

The rear stock and grip (shown above) come from the commercial LUCID AR Stock Kit. But Forum member Brian V. custom-made this one-piece walnut forearm.
Forum member Brian V. (aka “Carbide”) wanted a new look for his “modern sporting rifle”. He was tired of looking at black plastic (or FDE, OD green) and aluminum components on his AR15. So he decided to fit wood “furniture” on the rifle. He ordered a wood butt-stock and fore-arm set made by Lucid, but he didn’t like the two-piece fore-arm of the Lucid stock set. He decided he could build something better than the commercially-available, Lucid-made wood fore-arm.
Lathe-Turned Custom Walnut Sleeve in Front
So Brian took his existing AR tubular fore-arm and epoxied a walnut sleeve to it. With a lathe, Brian then turned the walnut sleeve to his desired dimensions: 2.250″ diameter in back and 2.200″ diameter in front, so there’s a little taper. Brian says “I could have gone a little thinner.” The wood fore-end was then sanded and stained to match the Lucid-made rear section. Brian says “the stain is not quite a perfect match, but but it looks a lot better.”
Does Brian like his new wood-stocked AR? Absolutely. He says the conversion makes the gun more user-friendly: “The wood is warmer to carry in winter and quieter.” He adds that the wood sleeve added about four ounces of weight to the fore-end, but that did not affect the handling.
We think this is a good “do-it-yourself” project that could be done by many of our readers. You can simply install the Lucid stock set or customize the front end like Brian did. Either way, you end up with a good-looking rifle that feels better in your hands.
Establishing zero at 300 yards. Dennis says: “Wow you can really drive that crosshair into the center of the bull with ease” with the 4.5X optic.
Dennis Santiago recently received the all-new Nightforce Competition SR Fixed 4.5x24mm Service Rifle scope. He will be using this at Camp Perry soon, so he needed to get zeros (and click values) for all his yardages. Off he headed to the Burbank Rifle and Revolver Club (BRRC) for a Zero Session.
After establishing a 100-yard, base-line zero from the bench, Dennis put on his sling and jacket to work out to 200, 300, and 600 yards. When shooting at 200, Dennis said: “The target is huge in that 4.5X scope. Fun to drive. Next stop NRA Week at Camp Perry!”
Above you can see Dennis working up two elevation zeroes for 600 yards. First he fired a center hold using the crosshair inside the circle to “pie” the bull. Next, he shot with a 12 o’clock hold using the lower leg of the crosshair to bisect the target. You can see the target at 600 yards in the top right of the photo.
Zeroing Task accomplished, Dennis is ready to take this rifle to Camp Perry for the National Championships. He says: “In the end, it’s always about your handy-dandy notebook.”
New 2016 CMP/NRA Rules Allow 4.5X Optics
Dennis Santiago explains the Service Rifle rule changes that now allow scopes up to 4.5X max magnification (and max 34mm objective):
“Per the 2016 Rulebooks of the CMP and NRA, today’s Service Rifle is now defined to include an M-16/AR-15 variant with an optical sighting system not to exceed 4.5X magnification. So, this optic-equipped rifle goes head-to-head with the match-tuned M-16A2/AR-15A2 iron sight guns in the same class. The rules were updated to take into account that some military branches no longer train service members to shoot iron sights as their primary marksmanship method and have switched to reliance combat optics. The rules were debated and tried in 2015 and codified at the beginning of this year. This will be the first Nationals where the old and new generation guns compete side-by-side.
Here is my personal prediction: There will be improved scores by Expert class shooters who figure out how to work with optics jumping into Master class. At the High Master level, there may be a slight rise in numerical scores but there will be a massive jump in X-Count. EICs will remain the all-out race they’ve always been; whoever makes the fewest mistakes wins the day.”

California Governor Jerry Brown just departed for a luxurious European vacation. But before he left the state, he savaged the Second Amendment rights of millions of California gun owners. Less than 24 hours after they arrived on his desk, Brown signed six anti-gun bills railroaded through the Democratic-controlled California Legislature. Among the bills signed by Brown was SB 1446 which will require Californians to forfeit, destroy, or ship out of the state ALL firearms magazines that can hold more than ten rounds. Owners of legally-obtained magazines, previously “grandfathered”, will receive no compensation though they must give up their property. Those who fail to comply will be fined and charged with an infraction, a low-level crime. This magazine restriction goes into effect July 1, 2017.
Gov. Brown also signed SB 1235 which will require background checks for the purchase of any and all ammunition. Ammo buyers’ names and personal information will be logged and tracked in a database.
Notice from NSSF RE California Legislation
The NSSF issued this statement: “The National Shooting Sports Foundation is extremely disappointed that Gov. Brown today chose to sign into law these highly restrictive and unneeded gun control measures, all of which will affect law-abiding Californians while doing nothing to stop the criminal misuse of firearms. By acting within 24 hours after being sent these bills, and not allowing the public to voice their opinions in order to depart for his European vacation, the governor compounded the miscarriage of legislative process and procedure while demonstrating disdain for Californians who now face laws that clearly infringe on their Constitutional rights.”
Gov. Brown SIGNED the following bills into law:
AB 1135 (Levine) and SB 880 (Hall) Firearms: Assault Weapons – Expands the definition of assault weapons based on whether a semiautomatic firearm has a detachable magazine, banning thousands of popular firearms.
SB 1235 (de Leon) Ammunition – Requires authorization to purchase ammunition and track what and how much ammunition each person buys, creating a database of ammunition purchasers.
SB 1446 (Hancock) Firearms: Magazine Capacity – Makes it illegal to possess magazines capable of holding more than 10 rounds no matter how long a person has owned them.
AB 1511 (Santiago) Firearms: Lending – Makes it illegal to loan a firearm to a person who is personally known to you (except for family members with restrictions).
AB 1695 (Bonta) Firearms: False Reports – Creates a 10-year prohibition on owning firearms for someone convicted of falsely reporting a lost or stolen firearm.
Gov. Brown VETOED the following bills:
SB 894 (Jackson) Firearms: Lost or Stolen: reports – Would have made it a crime not to report lost and stolen firearms to law enforcement within the arbitrary time limit.
AB 1673 (Gipson) Firearms: Unfinished frame or receiver – Would have expanded the definition of a firearm to include partially finished frames and receivers (no definition of what this means) and require their registration.
AB 1674 (Santiago) Firearms: Transfers – Would have made it illegal to buy or receive more than one firearm in any 30-day period.

Wouldn’t it be cool if you could adjust the bolt cycling energy on your AR-platform rifle? Turn down the cycling rate for slow fire at the bench or varmint hunting. Crank up the energy for 3-Gun matches and rapid-fire disciplines. This IS possible with a handy accessory that fits on your barrel. Wilson Combat offers an Adjustable Lo-Profile AR Gas Block for direct gas impingement AR-type rifles. Wilson Combat’s adjustable gas block replaces a standard AR gas block and allows you to tune your AR’s gas system for smoother cycling and enhanced reliability. Wilson Combat explains: “Adjusting your rifle’s gas port will lower or increase your bolt’s cyclic rate. This tailors your rifle’s performance to your unique needs.”
A simple adjustment of the hex screw at the front of the block modulates the gas volume allowing you to tune your rifle’s function to your favorite loads. This is very handy when shooting non-standard AR calibers, unusual hand-loads, or suppressed rifles. Adjustable Gas Block systems are sold as complete kits starting at $74.95. Wilson Combat offers two diameters (.750″, .937″) and three lengths (Carbine Length, Mid-Length, & Rifle Length), so you can select the right dimensions for your rifle configuration and barrel diameter. The blocks are Chromoly steel with a Melonited finish.
