Most bolt-action rifle shooters work the bolt with their trigger-pulling hand. This is because most rifles sold to right-handed shooters come with right-side bolts, while “lefty” rifles come with left-side bolts. This “standard” configuration requires the shooter to take his dominant, trigger-pulling hand off the stock to cycle the bolt, then re-position his hand on the stock, and “re-claim” the trigger. Often the shooter must lift or move his head to work the bolt, and that also requires him to re-establish his cheek weld after each and every shot. Not good.
This really doesn’t make much sense for precision shooting with fore-end support*. There is a better way. If you leave your trigger hand in position and work the bolt (and feed rounds) with the opposite hand, then you don’t need to shift grip and head position with each shot. All this requires is a weakside-placed bolt, i.e. a left bolt for a right-handed shooter or a right bolt for a left-handed shooter. The video below shows a “Lefty” working a right bolt. Note how efficient this is:
As our friend Boyd Allen explains: “If you think about it, if you are going to work with a factory action where your options are left bolt and left port or right bolt and right port, and you are building a rifle that will only be shot from a rest, using the left/left for a RH shooter or using a right/right for a LH shooter works better than the conventional configuration”.
Shoot Like a Champ and Work the Bolt with Your Weakside Hand
Derek Rodgers, the current F-TR World Champion, the reigning King of 2 Miles, and the only person to have won BOTH F-Open and F-TR U.S. National Championships, runs this kind of “opposite” bolt set-up. Yep, Derek shoots right-handed with a left bolt. Though Derek is a right-hander, he shoots with a Left Bolt/Left Port (LBLP) action. He pulls the trigger with his right index finger, while working the left-side bolt with his left (weakside) hand. This allows him to stay in position, and maintain his cheekweld. He places his right hand on the grip, while manipulating the bolt (and feeding rounds) with his non-trigger-pulling hand.
Current King of 2 Miles (and F-TR World Champion) Derek Rodgers
This is the rifle with which Derek won the 2013 F-TR National Championship.
*For true standing, off-hand shooting (whether in competition or on a hunt), a conventional strongside bolt placement makes sense, since the non-dominant arm must support the front of the rifle all the time. When shooting from bipod or rest, it’s a different story.
Here is beautiful F-Open rig crafted by Forum member CigarCop of KW Precision LLC. It features a laminated wood stock with stunning figured walnut on the outside.

New 600/1000 Benchrest Light Gun for Richard Schatz in 6 BRA
This blue benchrest rig was crafted by Alex Wheeler for ace benchrest competitor Richard Schatz, a past 600-yard IBS Shooter of the Year. Richard’s new 600/1000-yard Light Gun features a Krieger barrel chambered in 6 BRA (40° Ackley version of 6mmBR Norma). That Krieger is mated to a 1.550″ BAT B action, ignition-timed for smooth bolt close and increased accuracy. The trigger is the sophisticated Bix’n Andy. Schatz’s BAT is glued and screwed into a Wheeler LRB stock, with aluminum rails and adjustable metal “tracking rudder” on the toe of the stock. The rudder can be adjusted side to side to ensure optimal tracking, while the rudder’s vertical angle can be adjusted slightly with shims.
Hand-Crafted Thumbhole-Stocked Rifle Chambered in 6 PPC
Forum Member Grimstod offered this handsome 6 PPC custom with a beautiful, hand-made thumbhole stock: “This was fully accurized with Premier Accuracy recoil lug installed. Really makes these shoot a lot better. It features a Kelbly Panda action with Hart barrel and glass bedding. Trigger fall was perfect to start and we have to give Ian Kelbly big thumbs up for making every action perfectly timed.” On top is a March competition scope. See more photos at www.premieraccuracy.com.
A Wicked Accurate Big Dawg in 28 Nosler
This 28 Nosler Benchrest rifle looks good and shoots even better — check out that 20-shot target shot at 200 yards! You can’t argue with that…
Belonging to Forum member LA50Shooter, this rig is chambered in 28 Nosler, with metal work by Gre-Tan Rifles. The action is a BAT Model “L” 1.650 Octagon with a 30 MOA scope rail, running a Jewell BR Trigger. The stock, from D&B Supply, is a Shehane Big Dawg Tracker with 5″ fore-end. Color scheme is “Field & Stream” Rutland laminate. This big rig boasts FOUR 34″ Benchmark barrels (1.5″ for seven inches tapering to 1.225″ at muzzle).
A Pair of Score Benchrest Beauties
Forum member JimPag showcased two new Benchrest-for-Score rifles. The rig on the left, smithed by Dwight Scott, features a Farley Black Widow RBLPRE (with Bix’n Andy trigger). It features Pistachio and Carbon Terry Leonard stock glued and screwed by Sid Goodling. The barrel is a Krieger 23.5″ chambered in 30BR with a Mike Ezell tuner. It’s topped with a Goodling-built 1-piece Davidson base and a Nightforce 42X Comp scope. The rifle on the right, smithed by Sid Goodling, features a Marsh Saguaro RBLPRE Action with Bix’n Andy trigger, and March 36-55X scope. This rifle boasts a rare Screwbean Mesquite and carbon stock by Terry Leonard. The 23″ Lilja bbl is chambered in 30 Thrasher with a Goodling tuner. (30 Thrasher is longer 30 BR case developed by Joe Entrekin). Jim also has two other barrels for this action in 30 BR and 6 BRAI. On top is a Sid Goodling-built one-piece Davidson base with a March 36-55X scope.
Rem 700 in Manners Stock — .284 Winchester for Hunting
Here’s a Rem 700 enhanced with a Manners Elite TA stock and other upgrades. Forum Member NickB1075 says: “Here is a rifle I finished for hunting this year. It’s a bit heavy for New York woods carry but it just shoots great. Maybe I will have to get one of those fancy Proof Research barrels to lighten it up a bit.” Nick is running a Benchmark 1:8.5″-twist barrel chambered in .284 Win with 0.315 neck for shooting 150gr Barnes bullets. Nick added a Jewell trigger and on top is a U.S. Optics B10 Scope.
When Only the Biggest and Boldest Will Do — .50 BMG
No “Pride and Joy” feature would be complete without a Big Boomer. This impressive .50 BMG, “61 inches of big bore goodness”, weighs a whopping 49 pounds (95 lbs. complete with case and accessories). This rifle’s proud owner, forum member 6MT, says everything on this black beast is jumbo-sized: “Yes, I can stick my finger clear through the ports in the muzzle brake!” The rifle boasts a U.S. Ordnance 31″ heavy-contour barrel fitted to Barnard GP action. The stock is a “Big Mac” from McMillan. No optics yet — 6MT says he is “looking at an ATACR 7-35x56mm with a Spuhr mount… As soon as my wallet recovers!”
Gun-makers and barrel builders have adopted aerospace technology, using carbon fiber in their stocks and composite barrels. At SHOT Show 2018, we saw carbon applications on dozens of rifle brands. Some rifles sported full carbon stocks AND carbon-wrapped barrels. Others sported a carbon stock with steel barrel, or a carbon-wrapped barrel in a conventional stock. Carbon is definitely here to stay. This advanced material allows rifles to be lighter yet stronger. The advantages for the hunter in the field are real — a carbon-wrapped barrel can save quite a few pounds. Here are some of the most notable carbon applications we saw at SHOT Show.
Sako 85 Carbon Wolf
Possibly the best-looking carbon-stocked rifle at SHOT Show was the Sako 85 Carbon Wolf, featured in our Top Photo. New for 2018, this rifle features a full carbon composite stock, with the signature carbon fiber weave visible throughout. We found this new-for-2018 rig very ergonomic and nice to handle. The advanced-design RTW carbon fiber stock offers quick, push-button adjustments for comb height and LOP. Though not carbon-wrapped, the conventional 24″ blued steel barrel is fluted, reducing the overall weight of the rifle. Without optics, this rifle weighs well under 8 pounds. We were impressed by the Carbon Wolf, but choked on the steep $3600.00 MSRP. Street price will be lower — EuroOptic.com is listing a $3148.00 price for the Sako 85 Carbon Wolf.
The Firearm Blog says: “The stock features Soft Touch coating. Is is not at all slippery or loud like some carbon stocks can be. The barrels are factory threaded as well. Both the weight and the balance of the Carbon Wolf rifle felt perfect. I may have to add one to my Finnish rifle collection.” This is offered in 6.5 Creedmoor, .308 Win, .30-06 Sprg, 7mm Mag, and .300 Win Mag.
Nosler M48 Long-Range Carbon Rifle
Nosler recently introduced the M48 Long-Range Carbon rifle with the addition of a PROOF Research, carbon fiber-wrapped, match-grade barrel that significantly reduces the overall weight of the rifle. The carbon-wrapped Proof barrel is mated to a trued M48 receiver and bedded in a Manners MCS-T carbon fiber-strengthened stock. Nosler says: “The Model 48 Long-Range Carbon is an excellent choice for mountain hunting, backcountry excursions and long range competition where weight is a concern.” Initially, this rifle will be offered for 6.5 Creedmoor, 26 Nosler, 28 Nosler, 30 Nosler, .300 Win Mag, and 33 Nosler.
Christensen Arms TFM — Carbon Galore for 7.3-lb Rifle
As you can see there’s a whole lot of carbon fiber in the Christensen Arms TFM rifle. With a carbon-wrapped barrel and full carbon-fiber stock, this handsome rig weighs just 7.3 pounds (short action) or 7.8 pounds (long action). The carbon-wrapped stainless barrel and fully-adjustable Aerograde carbon-fiber stock are mated to a precision-machined action via integrated carbon fiber pillars. In addition, the TFM includes an integrated, 20-MOA optics rail, detachable magazine, and a titanium side-port brake. Impressively, Christensen Arms guarantees 0.5 MOA (half-MOA) accuracy.
Manners Full-Carbon F-Class Stock
For many years now, Manners Composite Stocks has offered an ultra-stiff, Low-Profile ‘Fish Belly’ F-Class Stock. The shell is 100% carbon fiber with a very long, stiff fore-end. From the back of the action to the tip of the fore-end the stock measures 27″ long which is around 7 1/2″ longer than the Manners T4 stock. The idea is to provide a longer wheelbase to better balance the long, 30-32″ barrels favored by many F-Class competitors. The front half of the fore-end is very thin (from top to bottom) to achieve a low profile on the bags. Much thought has gone into controlling fore-end flex. The stock achieves greater vertical rigidity (less deflection under load) through an innovative “fish belly” design. The rounded undersection, like a canoe hull, strengthens the fore-end considerably.
Weatherby Mark V with Carbon-Wrapped Barrel
Weatherby now offers rifles with Proof Research carbon fiber-wrapped barrels. The aerospace-grade carbon fiber in the Mark V Carbon barrel makes the barrel up to 64% lighter than traditional steel barrels of the same contour. Weatherby claims the carbon-fiber technology improves heat dissipation — so the barrel does not heat up as quickly with extended strings of fire. The 26” #4 contour carbon-wrapped barrel has a cut-rifled, hand-lapped 416R grade stainless steel core with a flush thread cap and 5/8-24 muzzle threads. It’s finished in tactical grey Cerakote. The Mark V Carbon carries Weatherby’s SUB-MOA (at 100 yards) accuracy guarantee when used with Weatherby factory or premium ammunition.
Carbon Edge from Fierce Firearms
Fierce Firearms also offers a long-range hunting rig with a carbon-wrapped barrel. This is an extremely light rig. Without scope or optional muzzle brake, the short-action version weighs just 6.4 pounds. It is available in Black/gray, Green/black and a variety of Camo finishes including Kryptec Highlander and Typhon patterns. All this lightweight tech doesn’t come cheap. The Carbon Edge retails for $3250.00 and a left-hand version is $250.00 more. Fierce does offer a 0.5 MOA (half-MOA) accuracy guarantee, which is something.
How Good Are Proof Research Barrels? — Commentary by Mike Davis
Over the past 15 years Davis Custom Rifle has installed barrels from most major barrel manufacturers. We are very fortunate to have such quality barrel makers. I think Proof Research falls into that top-of-the-line category. Proof Research carbon-wrapped steel barrels are super light-weight, yet offer rigidity and superb accuracy. I have used them for 22-250, 6mm/6.5mm Creedmoor, .308 Win builds and multiple long range hunting rifles in .280, .280 AI, .300 WSM, .300 Win Mag, 28 Nosler, and 30 Nosler. These builds with Proof Research barrels typically deliver quarter-MOA accuracy or better.
The Proof Research technology allows us to build lighter rifles with outstanding accuracy, easy cleaning, and the ability to shoot long strings without point of impact shift. It’s not hard to understand why hunting rifles with these capabilities are in high demand. Combined with other light-weight components (such as Titanium actions), it’s not difficult to get these rifles down to 6.25 to 7 pounds total weight before optics.
A past F-TR National Champion, James “Jimmy” Crofts is one of America’s top F-Class competitors. And now this F-TR ace has a stunning new rifle in his arsenal. AccurateShooter Forum member CigarCop, head honcho of KW Precision LLC, recently completed a new F-TR rig for Crofts. This handsome, state-of-the-art rifle features top-tier components: Borden action, twin Brux barrels, Cerus RifleWorks F-TR Stock, and Jewell trigger, all resting on a wide-base Phoenix Bipod.
James Crofts photo by Kent Reeve.
Have a good look at these photos below. Yes, envy is the appropriate reaction. With the smooth operation of the Borden action and the predictable accuracy of Brux barrels, we bet James’s new rig will shoot as good as it looks.
CigarCop actually chambered two barrels for James, with different fluting patterns — conventional linear flutes for one tube, and lines of staggered ovals for the other. Finished length for both barrels is 30″. Yes it looks cool, but the fluting was done mainly to save weight with the 30″-long lengths. CigarCop tells us the complete rifle, without scope and rings, weighs just under 15 pounds. Max allowed weight for an F-TR rifle, with scope, is 18.18 pounds (8.25 kg).
Weatherby Inc., a major name in the rifle business, is abandoning California, leaving the Golden State for friendlier climes in Wyoming. Based in Paso Robles, CA for many decades, Weatherby announced last week that it will relocate its production facilities and headquarters to Sheridan, Wyoming. The respected rifle manufacturer, founded in 1945, was welcomed by Wyoming state officials. In fact Wyoming Governor Matt Mead was present for Weatherby’s announcement, made at Shot Show 2018. By contrast, California’s state leaders, given their anti-gun bias, are no doubt happy to see Weatherby leave. The Democratic Party now controls both houses of California’s State Legislature, as well as the Governor’s office. Weatherby’s departure is just the latest exodus of a major firearms industry company from California. In the past year, Berger Bullets, now part of Capstone Precision Group, relocated from Southern California to Arizona.
“We wanted a place where we could retain a great workforce, and where our employees could live an outdoor lifestyle”, said Adam Weatherby, Chief Executive Officer. “We wanted to move to a state where we can grow into our brand. Wyoming means new opportunities. We are not interested in [just] maintaining — we are growing.”
Weatherby Leaves Hostile Political Environment
Is Weatherby’s Wyoming move all about dollars and cents? Not entirely. California has become increasingly hostile to firearms manufacturers. TheFireamRack.com’s Dan Zimmerman observes: “[Weatherby] wanted to do business in a state that isn’t at war with the very products they make. A state that respects the Second Amendment and won’t try to claw back every single cent it can wring out of businesses located there. So Weatherby made the entirely rational choice to take their company to a place that values what they do.”
The Wyoming Business Council heralded Weatherby’s relocation: “The move is expected to create 70 to 90 jobs and more than $5 million annually in payroll in the next five years.” Recognizing the benefits to Wyoming, Governor Matt Mead and the Business Council began recruiting Weatherby a year ago. Governor Mead declared: “Wyoming is a great place to do business and is excited to welcome Weatherby to Sheridan. For over 70 years, Weatherby has been an innovator in firearms design and manufacturing. The company will add to our manufacturing base and fit well with our diversification objectives.”
Weatherby will locate its new production facility in Sheridan, Wyoming. Sheridan is a beautiful location in Northern Wyoming, a verdant plain with mountains to the West. Sheridan has just under 18,000 residents. But there will be another 100 or so soon. Local County10 News reports: “Sources shared with County 10 that Weatherby, located in California since the mid 1940s, has been considering locating in a state with a more favorable pro-firearms industry culture and citing a frustration with California’s tax structure.”
Top Five Reasons Firearms Businesses Leave California
1. High California Taxes. California’s Corporate Tax Rate is 8.84% — among the highest in the nation. Wyoming, by contrast, has ZERO state corporate taxes. California Sales Tax starts at 8% while Wyoming Sales Tax ranges from 4-6%. California was ranked 48th overall (third worst) in Tax Climate by the Tax Foundation. Wyoming was rated Number One Overall (best). This ranking considers corporate tax, personal income tax, sales tax, and property tax.
2. High Cost of Living in California (all factors). It is expensive to live in California. One Cost-of-Living index rated Paso Robles, CA 144.5 compared to 101.8 for Sheridan, Wyoming (higher is worse). Another Cost of Living Calculator states that, including housing, Paso Robles, CA is 41.9% more expensive than Sheridan, WY. Ironically, howevever, median income in the two cities is not that different: $28,358.00 for Paso Robles (CA) vs. $26,491.00 for Sheridan (WY). Money definitely goes farther in Wyoming. In terms of buying power, one study suggests a $35,535/year salary in Sheridan, WY equates to a $50,000/year salary in Paso Robles, CA.
3. Bad Roads and Infrastructure in California. Among all states, California has the fourth worst roads in the country with 50% of roads in “poor condition”. In fact, the Los Angeles Regional area road system has been deemed the worst in the nation according to a Federal Highway Administration Report. By contrast, Wyoming’s highway system was ranked number one, best in the USA, in the 21st Annual Reason.org Highway Report. And this was despite the fact that state gas taxes per gallon are much less in Wyoming than in California*. California’s roads and infrastructure are only going to get worse as the population grows.
4. Anti-Business California State Government. California is now a one-party state, with the Democratic Party controlling the State Senate, State Assembly, AND the Governor’s office. This has created an anti-business governmental culture, with a left-leaning bias. California also has many more business regulations, and more restrictive gun and ammo laws. The situation is unlikely to change because there is undeniable evidence of massive voter fraud in California which favors Democratic candidates. For example, in Los Angeles County “the total number of registered voters now stands at a number that is a whopping 144% of the total number of resident citizens of voting age”, according to Judicial Watch. 10 other California counties have significantly more registered voters than voting-age citizens. (SOURCE: Judicial Watch Report.)
5. Out-of-Control California Housing Costs. Coastal counties in California have some of the highest average home prices in the country. The median home price in Paso Robles, CA is $486,100. By contrast, the median home price in Sheridan, WY is $217,100 — well under HALF the California price! And rental housing is cheaper in Wyoming too. Median Rent in Paso Robles, CA is $2150.00 per month, while Median Rent in Sheridan, WY is $1250.00 per month.

Can you list all the serious problems that excessive headspace can cause? For that matter, could you even explain what, exactly, is meant by the term “headspace”? If not, you should watch this instructional video from Brownells. This video defines the term “headspace”, explains why proper headspacing is critically important, and illustrates how headspace gauges work.
Headspace is a measurement from the bolt-face to a point in the chamber. This point of measurement will vary based on the type of cartridge. Improper headspace, either excessive or (conversely) under SAAMI specifications, can cause a variety of problems, many serious.
Problems Caused by Too Much Headspace
Excessive headspace issues can include: light primer strikes, failure to fire, bulged/blown cases, case separations, split shoulders, or unseated primers after firing. Case ruptures caused by excessive headspace can lead to catastrophic failures causing serious injury. That is why headspace is such an important measurement.
Problems Cause by Too Little Headspace
Insufficent (or excessively tight) headspace can prevent the firearm from going into battery, resulting in failure to fire or deformation of the cartridge case. Various feeding and functioning problems can be caused by cases with too little headspace, even if a round can be chambered (with effort).
A lot of claims are made about accuracy for AR-platform rifles, but much of that is just “sales talk”. But if you want a truly accurate black rifle, there are some key upgrades that, collectively, can transform a plain jane AR into a true tack-driver. Here’s an article by a genuine AR expert that will help you identify those components that really make a difference — the parts that can deliver true “match-grade” accuracy. Built right, a modern AR can deliver half-MOA accuracy with handloads. In this article, Robert Whitley of AR-X Enterprises explains how that’s done.
In our Shooters’ Forum, one member recently asked: “What makes an AR accurate? What parts on an AR can really affect accuracy — such as free-floating handguards, barrels, bolts, bolt carriers?” Robert Whitley posted a very comprehensive answer to this question, based on his experience building and testing dozens of AR-platform rifles. Robert runs AR-X Enterprises, which produces match-grade uppers for High Power competitors, tactical shooters, and varminters.
Building an Accurate AR — What is Most Important
by Robert Whitley
There are a lot of things that can be done to an AR to enhance consistent accuracy, and I use the words “consistent accuracy” because consistency is a part of it (i.e. plenty of guns will give a couple great 5-shot groups, but won’t do a very good 10- or 20-shot groups, and some guns will shoot great one day and not so good on others).
Here are 14 key things we think are important to accuracy.
1. Great Barrel: You’ll want a premium match-grade barrel, well-machined with a good crown and a match-type chambering, true to the bore and well cut. The extension threads must also be cut true to the bore, with everything true and in proper alignment.
2. Rigid Upper: A rigid, heavy-walled upper receiver aids accuracy. The typical AR upper receiver was made for a lightweight carry rifle and they stripped all the metal they could off it to make it light to carry (which is advantageous for the military). The net result are upper receivers that are so thin you can flex them with your bare hands. These flexible uppers are “strong enough” for general use, but they are not ideal for accuracy. Accuracy improves with a more rigid upper receiver.
3. True Receiver Face: We’ve found that truing the receiver face is valuable. Some may argue this point but it is always best to keep everything related to the barrel and the bore in complete alignment with the bore (i.e. barrel extension, bolt, upper receiver, carrier, etc.).
4. Barrel Extension: You should Loctite or glue the barrel extension into the upper receiver. This holds it in place all the way front to back in the upper receiver. Otherwise if there is any play (and there typically is) it just hangs on the face of the upper receiver completely dependent on the face of the upper receiver as the sole source of support for the barrel as opposed to being made more an integral part of the upper receiver by being glued-in.
5. Gas Block: You want a gas block that does not impose pointed stress on the barrel. Clamp-on types that grab all the way around the barrel are excellent. The blocks that are pinned on with tapered pins that wedge against the barrel or the slip on type of block with set screws that push up from underneath (or directly on the barrel) can deform the bore inside of the barrel and can wreck the accuracy of an otherwise great barrel.
6. Free-Float Handguard: A rigid, free-float handguard (and I emphasize the word rigid) really makes a difference. There are many types of free-float handguards and a free-float handguard is, in and of itself, a huge improvement over a non-free-float set up, but best is a rigid set-up. Some of the ones on the market are small diameter, thin and/or flexible and if you are shooting off any type of rest, bipod, front bag, etc., a rigid fore-end is best since ARs want to jump, bounce and twist when you let a shot go, as the carrier starts to begin its cycle before the bullet exits the bore.
7. Barrel Contour: You want some meat on the barrel. Between the upper receiver and the gas block don’t go real thin with a barrel (we like 1″ diameter if it’s workable weight-wise). When you touch off a round and the bullet passes the gas port, the gas system immediately starts pressuring up with a gas impulse that provides vibrations and stress on the barrel, especially between the gas block back to the receiver. A heavier barrel here dampens that. Staying a little heavier with barrel contour through the gas block area and out to the muzzle is good for the same reasons. ARs have a lot going on when you touch off a round and the gas system pressures up and the carrier starts moving (all before the bullet exits the bore) so the more things are made heavier and rigid to counteract that the better — within reason (I’m not advocating a 12-lb barrel).
8. Gas Tube Routing Clearance: You want a gas tube that runs freely through the barrel nut, through the front of the upper receiver, and through the gas key in the carrier. Ensure the gas tube is not impinged by any of them, so that it does not load the carrier in a stressed orientation. You don’t want the gas tube bound up so that when the gas tube pressures up it immediately wants to transmit more force and impulse to the barrel than would normally occur. We sometimes spend a lot of time moving the gas block with gas tube on and off new build uppers and tweaking gas tubes to get proper clearance and alignment. Most gas tubes do need a little “tweaking” to get them right — factory tubes may work OK but they typically do not function optimally without hand-fitting.
9. Gas Port Tuning: You want to avoid over-porting the gas port. Being over-gassed makes the gas system pressure up earlier and more aggressively. This causes more impulse, and increases forces and vibration affecting the top end and the barrel. Tune the gas port to give the amount of pressure needed to function properly and adequately but no more.
10. Front/Back Bolt Play: If accuracy is the game, don’t leave a lot of front/back bolt play (keep it .003″ but no more than .005″). We’ve seen factory rifles run .012″ to .015″ play, which is OK if you need to leave room for dirt and grime in a military application. However, that amount of play is not ideal for a high-accuracy AR build. A lot of front/back bolt play allows rounds to be hammered into the chamber and actually re-formed in a non-consistent way, as they are loaded into the chamber.
11. Component Quality: Use good parts from a reputable source and be wary of “gun show specials”. All parts are NOT the same. Some are good, some are not so good, and some aftermarket parts are simply bad. Don’t be afraid to use mil-spec-type carriers; by and large they are excellent for an accuracy build. Also, remember that just because a carrier says “National Match” or something else on it does not necessarily mean it’s any better. Be wary of chrome-plated parts as the chrome plating can change the parts dimensionally and can also make it hard to do hand-fitting for fit and function.
12. Upper to Lower Fit: A good upper/lower fit is helpful. For quick and dirty fit enhancement, an Accu-Wedge in the rear helps a lot. The ultimate solution is to bed the upper to a specific lower so that the upper and lower, when together, are more like one integral unit. For the upper receivers we produce, we try to get the specs as close as we can, but still fit the various lowers in the market place.
13. Muzzle Attachments: Don’t screw up the muzzle (literally). Leave as much metal on the barrel at the muzzle as you can. People like to thread the muzzle for a flash hider, suppressor, muzzle brake, or some other attachment, but if you really want accuracy, leave as much metal as you can there. And, if you have something that screws on, set it up so that it can be put on and have it stay there without putting a lot of torque and stress on it right where the bullet exits the bore. If you are going to thread the end of the barrel, make it concentric with the bore and make sure what you screw on there is as well. For all muzzle attachments, also ensure that the holes through which the bullet passes through are dead true to the bore. Many aftermarket screw-on things are not so good that way. Anything that vents gas should vent symmetrically (i.e. if it vents left, it should vent equally right, and likewise, if it vents up, it should vent down equally). Uneven venting of gas can wreck accuracy.
14. Quality Ammunition: Ammo is a whole story by itself, but loads that are too hot typically shoot poorly in an AR-15. If you want accuracy out of an AR-15, avoid overly hot loads. Shown below are test groups shot with four (4) different uppers, all with moderate loads. These four uppers all pretty much had the same features and things done to them as explained in this article, and they all shot great.
This stunning Celtic Engraved Double Bolt Action rifle is from Fuchs Fine Guns.
As a New Year’s gift to our readers, we thought we’d share some beauty pictures — rifle beauty that is. In our Shooters’ Forum, a Gun Glamour thread recently started entitled: “Show me what a beautiful gun looks like!” Well here are some very handsome rifles featured in that Forum Thread. Enjoy.
Beautiful Rifles from our Shooters’ Forum
Forum member Kurz posted a dream gun owned by a friend in England. Kurz included a quote from a book created by the rifle’s owner: “There, with my father’s words ringing in my ears, I shall take that ‘step forward’ and order a perfect machine based on the Mauser ’98 action, built from metal and wood by master craftsmen who truly understand that ‘reliable’ and ‘mechanical integrity’ have as much relevance today as they did all those years ago.”
A gun can “shoot dots” and still be handsome. Here is a short-range benchrest rifle with a stunning, exhibition-grade Walnut stock. Forum member Josh B found this beauty.
This “old school” rimfire sports a Stolle Swindlehurst Chrome Moly action, Unertl 20X scope, Krieger barrel, and Kelbly trigger. Forum Member FFEMT tells us this rifle “has a nice little piece of English Walnut”. Yes indeed — the stock is from John Maxon
Forum member JRS submitted a stunner from Europe. This beauty features a truly exquisite piece of wood with elaborately engraved receiver. It also has escutcheons and special metal work on the grip.
Lever-action Falling Block rifles can be beautiful too. This one features a color case-hardened receiver and handsome two-piece fancy wood stock. This was submitted by Forum member Kurz who notes: “Besides exhibition grade walnut, I like the variations available in spalted maple for rifle stocks.”
A competition rifle must be “performance first”. But that doesn’t mean they can’t be handsome too. Forum member XTR’s rifle, an F-TR rig, features Maple wood with Bubinga tips.
“Wood is Good” — as demonstrated by all the rifles showcased above. But, as a “parting shot”, we’ll add a blue British beauty from the long-running Pride and Joy Forum Thread we started a decade ago. This eye-catching 270-7mm WSM F-Classer belongs to Forum member Elwood from the UK. A well-executed hydro-dip finish can really dress up a competition rifle.

Wouldn’t it be cool if you could shoot .22 LR rimfire ammo from your regular hunting/tactical rifle. That would be ideal for low-cost training right? Well, this IS possible, provided you have a rifle that was designed with a .22 LR conversion in mind. One such firearm is the Sauer 202 from Germany. This impressive centerfire rifle is available with a factory-engineered .22 LR rimfire conversion. Read on to learn how it works…
Sauer 202 Rifle: .308 Win/6.5×55 with .22 LR Conversion
Forum member “Tooms” sent us a report on his very special Sauer 202 with a .22 LR conversion kit. Sauer 202 rifles feature a “Quick-change barrel system”. The barrel is clamped into the receiver with crossbolts providing tension. This allows barrels to be swapped in a few minutes with simple tools. Tooms, from Denmark, explains: “The rifle began as a Sauer 202 Avantgarde Gold in .308 Win. I have added a 6.5×55 match barrel, plus a wide flat-bottom match fore-arm with rail for handstop and bipod. The .22 LR system [originally] cost $1000.00 [including] barrel, bolt, magazine well assembly, and magazine. The barrel is attached by three cross-bolts and the magazine well assembly is attached by one screw that fits into the barrel.”
Using this “Quick-change system”, Tooms can easily remove his centerfire barrel and swap in a .22 LR barrel. Then he places the factory conversion kit into the magazine well. This kit provides a rimfire bolt, a fitted sleeve for the rimfire bolt, and a magazine housing. This is a full Sauer factory-designed system so it works flawlessly. With the bolt closed, you can see the “new” .22 LR chamber in the front section of the loading port. On the silver section of the bolt you can see the rimfire extractor on the side.
The 22LR Conversion Really Works
The Sauer 202 Varmint rifle shoots very well with the 22LR conversion, as the 50m target at right shows. Though quite expensive, the conversion kit essentially transforms your centerfire rifle into fully functional, mag-fed precision rimfire. That makes the Sauer 202 much more versatile as a hunting platform. It also allows you to cross-train with inexpensive ammo. You don’t have to purchase another scope, trigger, or stock. And you enjoy the exact same stock fit and ergonomics whether you’re shooting centerfire or rimfire. In some countries where gun ownership is severely restricted, it may be easier, from a legal standpoint, to purchase a 22LR conversion kit than to obtain a permit for a second rifle.

5. Gas Block: You want a gas block that does not impose pointed stress on the barrel. Clamp-on types that grab all the way around the barrel are excellent. The blocks that are pinned on with tapered pins that wedge against the barrel or the slip on type of block with set screws that push up from underneath (or directly on the barrel) can deform the bore inside of the barrel and can wreck the accuracy of an otherwise great barrel.
