Accurate, modular, and supremely versatile, the AR15 is America’s favorite semi-auto rifle. But let’s face it, the AR is a maintenance hog. The AR’s gas tube blows carbon and soot right into the middle of the bolt assembly where it cakes on to the metal. The AR bolt also has many tiny parts, and small recesses, which must be cleaned regularly. This author has seen numerous ARs fail simply because there was gunk (dried lube, carbon, brass shavings) in the ejector slot or extractor spring recess.
A Clean AR is a Happy AR — Whether You Run ‘Wet’ or ‘Dry’
There are various schools of thought when it comes to maintaining an AR. Some folks prefer to run their AR “dry” with minimal lube on the lugs and friction surfaces. Other shooters prefer to run their ARs “wet”, with lots of lube. But whatever your preference, you need to clean your AR regularly. And nothing is more important than the AR’s bolt/carrier assembly. Because it is involved in feeding, firing, and extracting, the AR-15 bolt/carrier assembly can be considered the most critical portion of the AR-15 from a maintenance standpoint.
Bolt Take-Down Guide on Top Quark Blog
The editor of the Top Quark Blog has created an excellent illustrated AR15 Bolt Take-Down Guide that shows how to disassemble an AR15 bolt and carrier for regular cleaning. Even if you’re an experienced AR15 shooter, you can learn something from this page (sample at right), and you may want to bookmark it for future reference. The photos are large and clear and there are helpful hints for each step of the process.
The author knows his stuff and offers some important insights. For example, he notes that “Extractor springs in most AR15 bolt assemblies are fairly weak, and this can lead to various extraction-related failures. One of the few high points about Colt assemblies is their usage of higher-strength extractor springs. You can tell the difference by looking at the inner plastic insert. ‘Normal’ springs feature a blue plastic insert, Colt strong springs have a black insert.”
There is one notable oversight on this page — the author doesn’t cover disassembly and cleaning of the ejector assembly. This is actually quite important. A few small brass shavings, combined with carbon and lube in the ejector slot, WILL cause malfunctions. In fact, when this editor is called to diagnose problem ARs, the first things I look at (after swapping magazines) are the ejector recess and the slot for the extractor. Clogged ejectors are responsible for fail-to-ejects and other jams. It is essential that you keep the ejector hole clean. Old, gooey lube residues mixed with carbon and tiny brass shavings in the ejector recess will create all sorts of problems. As shown in the diagram below, it is simple to remove the ejector (#6) and ejector spring (#5), by drifting the ejector retaining pin (#4).

This week, Shooting USA TV spotlights the 2020 GAP Grind, the largest and most popular PRS Pro-Am Tactical match. The 2020 GAP Grind/Bushnell Pro/Am took place last October at the K&M Precision Shooting Complex in Finger, Tennessee. The 3-day event, the biggest PRS match of the year, included professional and “amateur” classes with both individual and team competition. Competitors ranged from top professionals to those shooting their first-ever tactical match.
SHOW TIMES: This Shooting USA Episode airs Wednesday, August 4, 2021 at 9:00 PM Eastern and Pacific; 8:00 PM Central. If you miss the regular broadcast, you can stream the show at any time on Vimeo for $0.99 per episode.
The GAP Grind is held at the impressive K&M Shooting Complex in Tennessee:
Lots of Action, with 20+ Stages
The GAP Grind is a challenging, “high tempo” match with minimal down-time between stages. Over the course of 20+ stages, competitors will fire 200+ shots at a variety of steel, paper, moving, and reactive targets out to 1,200 yards. Targets vary in size/difficulty based on the shooter’s position, distance, and time allotted. Most stages include “stressors” — i.e. time limits or required movement(s).
The GAP Grind typically attracts over 300 competitors — half experienced shooters and the other half newcomers to the sport. The key to growing the shooting sports is attracting new shooters. The best way to bring in “new blood” seems to be the Pro-Am type format. At the GAP Grind, experienced shooters share their knowledge and guide the new shooters through the competition.

GAP Grind Hardware
You’ll find the latest and greatest PRS hardware at the GAP Grind. Notable in 2019 was the fact that many top competitors “stepped down” from the 6.5/6mm Creedmoor to the smaller, more efficient 6mm Dasher, 6BRA and other 6mm cartridges. The Dasher offers excellent accuracy with less recoil than the 6.5 Creedmoor. Also, many top shooters are now running Kahles optics. Photo by Shelley Giddings.

For more accurate rifle handloads, you can throw the charge within a grain and then trickle up to the final load weight using using a scale and separate trickler.
On the 6.5 Creedmoor Facebook page we found an eye-catching Savage Model 10 BA Stealth. Rifle owner Derek P. has done some important upgrades, starting with a wicked, spiral-fluted McGowen barrel with red-painted flutes. The red theme was carried over to the chassis which combines fire-engine red with matte black in the middle. The scope rings and even the magazine were painted red to match as well. The whole effect is very striking, as you can see.
The barrel is a 29-inch 1:8″-twist McGowen. The optic is a 4.5-27x56mm Vortex Razor HD GenII with sunshade. That supper-stable rear sandbag is a Protektor DR Bag, one of our favorites. The front sandbag is also a Protektor. The front Rest is the new Protektor Aluminum Rest with Mariners Wheel. Look carefully and you’ll see a flat 2.5″-wide block on the underside of the forearm. That improves stability and tracking.
What we really like is the upgraded rear buttstock section. This is NOT standard by any means. Rifle owner Derek has fitted an aftermarket XLR Tactical Lite Buttstock that sits properly in that Protektor DR rear bag. This unit combines an adjustable buttpad with a nice cheek-rest (with upgraded pad from Tactical Works). And, very importantly, the XLR can be fitted with a “tactical bag rider” or you can easily make your own bag rider.
As the Savage 10 BA Stealth Comes from the Factory
This video shows a box-stock Savage 10BA Stealth. Note how different the stock buttstock/cheekpiece assembly is compared to Derek’s Red Hot Savage.
Thinking of getting started in the Practical/Tactical shooting game? Looking for ways to be more stable when shooting from unconventional positions? Then you may want to read Marcus Blanchard’s Practical Shooter’s Guide (A How-To Approach for Unconventional Firing Positions and Training). Unlike almost every “how to shoot” book on the market, Blanchard’s work focuses on the shooting skills and positions you need to succeed in PRS matches and similar tactical competitions.
Blanchard provides clear advice on shooting from barricades, from roof-tops, from steep angles. Blanchard says you need to train for these types of challenges: “I believe the largest factor in the improvement of the average shooter isn’t necessarily the gear; it’s the way the shooter approaches obstacles and how they properly train for them.”
Blanchard also offers good tips on shooting fundamentals. Here’s an example:
Blanchard on Trigger Control
“There will always be some amount of wobble when shooting in positions other than prone, and timing the shot to go off when the reticle is within the target is difficult to accomplish when poor trigger techniques are employed. The most common [mistake] I have seen is ‘slapping’ the trigger. The finger is usually hovering off the trigger, and when the shooter determines that NOW is the time to fire, they quickly pull their finger to the rear and ‘slap’ the trigger. The finger never pulls the trigger in the same place and often provokes a sympathetic contraction of the rest of the muscles in the hand, which results in unwanted movement before the bullet exits the muzzle.”
Author Marcus Blanchard has the credentials. A Marine Corps veteran, Blanchard is a regular Top 10 finisher in Precision Rifle Series events. In 2015 Blanchard was ranked 8th overall (nationwide) in the PRS series at year’s end. In 2016 Blanchard won the New Mexico Precision Rifleman’s Championship.

6.5 Guys Recommend Practical Shooter’s Guide
The 6.5 Guys have reviewed Blanchard’s book and they recommend it highly: “What’s a good book for the beginning shooter who wants to get into long range precision rifle or the intermediate shooter who wants to improve his scores? [The Practical Shooter’s Guide] is particularly useful because it explores firing from various positions and props that are encountered in long range precision rifle [events]. This knowledge is completely missing from more traditional books where the shooter is usually slung up and shooting at a paper target. Marcus… goes into considerable detail about shooting from rooftops, reverse rooftops, side slopes, tank traps, barricades etc. This is the type of information that is very difficult to find. We consider ourselves reasonably knowledgeable shooters and this book provided us with new and useful information.” CLICK HERE for 6.5 Guys REVIEW.
6.5 Guys Review Marcus Blanchard’s Practical Shooter’s Guide
Former USMC scout-sniper Frank Galli explains that there is no voodoo when it comes to precision rifle marksmanship, but there ARE techniques that, when practiced, make the difference between good marksmanship and great marksmanship. Understanding the reasons that a bullet hits or doesn’t hit its intended target at ultra-long distances is a crucial element to learning.
Galli’s explanations of how to understand and compensate for wind speed and direction are excellent. In this book, Galli offers great wind-reading advice.
Published in 2020, Galli’s treatise is four years newer than Blanchard’s book, so it includes more of the latest gear and equipment. Galli’s book covers the fundamentals of precision marksmanship with easy-to-understand methodology. The book follow the same instruction process Galli uses in his live marksmanship classes (CLASS REPORT HERE).
Published in 2020, this well-illustrated, 272-page book covers the latest equipment (scopes, LRFs, chassis systems, magazines, bags, bipods, tripods) favored by tactical competitors in PRS/NRL type matches.
Looking for a match-worthy PRS/NRL rig for under $1750.00? Check out Savage’s Elite Precision Model 110. GunsAmerica Digest recently did a very thorough test of the 110 Elite Precision, declaring that this modern Savage is “Competition-Ready Out of the Box.” The Savage’s $1750 price is well under the PRS $2500 Production Division limit.*
Is this an outstanding deal at $1750? Absolutely. Consider this, the recently-released Proof Research MDT Chassis Rifle, which shares the SAME MDT ACC Chassis, has a $5699.00 MSRP! For that amount of hard-earned cash, you could buy THREE Savage Elite Precisions AND have $449 left over ($1750 x 3 = $5250)! Put the $3949 saved into optics and reloading gear (or a couple mortgage payments).
The Savage 110 Elite Precision has many notable features:
1. Modular Driven Technologies (MDT) Adjustable Core Competition (ACC) Chassis
2. Trigger adjusts from 1.5-4.0 pounds
3. Barrel comes with timed muzzle brake from factory
4. MDT ACC Chassis easily accepts Weights and Accessories
5. Takes AICS-compatible Magazines
6. Titanium Nitride coated bolt body
This rifle boasts an excellent MDT ACC modular chassis. GunsAmerica stated: “Combined with the excellent trigger, an AR-compatible vertical grip, flared magazine well, and AICS mag system (along with a host of additional features), the 110 Elite Precision comes with everything you need [for PRS/NRL matches].” The stock has ARCA rails on the fore-end and M-LOK mounting points for accessories and/or weights. You can add an additional 9 pounds of steel to customize the balance/mass of the rifle to improve stability and minimize recoil.
The Cheekpiece and Buttpad are adjustable, along with Length of Pull (LOP).
Another reviewer noted that the 110 Elite Precision has important accurizing tweaks from the factory: “Key upgrades include a blueprinted action … Savage squared the receiver face and cleaned up the receiver threads to ensure they’re concentric with the barrel’s bore. This combination goes a long way in eliminating the occasional flyer that can ruin a good group or cause a miss in a match.” Source: GunsandAmmo.com.
Accuracy with Factory Ammo
What kind of accuracy can you expect? Decent for a factory barrel and factory ammo. With Hornady 6.5 Creedmoor ammo, shooting off a sled, the test rifle delivered 1.1-MOA average groups. We would expect considerably better accuracy using a proper front rest with a bag-rider fitted to the fore-end. Likewise, the gun would almost certainly shoot better with handloads with Lapua brass and Berger bullets. Handling was good: “The Elite Precision is about as shootable as it gets. The 12.6-pound rifle produces very little recoil with the 6.5 Creedmoor cartridge, and … the ACC chassis can be weighted to control recoil even further.” NOTE: We have discussed accuracy with other Savage 110 Elite Precision owners, who have reported considerably better accuracy. But as with most large-maker factory rifles, the accuracy of the barrel is unpredictable. If you want a half-MOA guarantee, you’ll need to spend more (see footnote).
Actual owners have been impressed with the 110 Elite Precision. One buyer posted: “You couldn’t build a complete PRS rifle that is this good of a platform for even close to the price!” GunsAmerica tester Jordan Michaels concurred that this rig is a great choice for PRS/NRL factory-class: “If you’re in the market for a rifle to compete in a long-range competition, the Savage 110 Elite Precision is an excellent choice.”
Here is a detailed examination of the Savage Elite Precision in 6mm Creedmoor:
* The PRS “Production Class” price limit is now $2500.00 as stated in the 2021 PRS Rulebook (Rule 2.3.1). To qualify as Production Class, the rifle must have that manufacturer’s stamp on the barrel, so you can’t cheat and slip a Krieger or Bartlein on the Savage (Rule 2.3.11). Another under-$2500 alternative is the newly-introduced MasterPiece Arms MPA BA PMR Pro Rifle II (Product Match Rifle) priced at $2499.00. This rifle, which comes with a Half-MOA Accuracy Guarantee, has been approved for use in PRS Production Division. The MPA includes many competition-related features while staying under the $2,500 price limit for this class. It is available in either a Black or Tungsten Cerakote® finish. It uses a MPA/Curtis Short Action with Lothar Walther hand-lapped barrel. MORE INFO.
One of the biggest PRS matches of the year was held recently. Nearly 200 shooters competed in the 2021 Hornady Precision Rifle Challenge, held July 9-10, 2021 at Hornady’s private 250,000 acre ranch property outside of Evanston, Wyoming, across the state line in Utah. The match featured 18 challenging stages. Course of fire consisted of 200 rounds with “off trail” walking between stages. Natural terrain and high winds made for an exciting match.
Run in Utah’s backcountry, the Hornady Precision Rifle Challenge is a unique long range competition with tough terrain and major elevation changes. This wasn’t a typical PRS Pro Series match by any means. Participants in this challenging Precision Rifle match encounter challenging conditions not typically seen in other tactical matches. And this year was particularly tough, with winds hitting 35 mph on the first day of the competition.
Hornady congratulates the following 2021 PRC division and class winners:
Open Division winner: Ken Sanoski
Top Production: Doug Koenig
Top Senior: Rick Reeves
Top Lady: Allison Zane Top
Tactical: Patrick Lorenzo
Top Mil/LE: Kahl Harmon
Top Gas Gun: Buck Holly
Top Junior: Jake Millard
Very High Winds at 2021 PRC Doug Koenig took first place in the Production Division shooting Hornady 6mm 110gr A-Tip® bullets. Koenig noted: “This match is one of the toughest in the country and on day one, we experienced 35 mph winds. I am unbelievably impressed with how well the A-Tip bullets handle wind.”
GA Precision’s George Gardner and Bryan Sikes were match directors. “The match would simply not be possible without the help of our amazing ROs and volunteers,” said Sikes. “In addition, [we thank] all of the sponsors that donated to this match — this is the biggest prize table we have ever had.”
This video, from last year’s PRC event, is well worth watching. It provides plenty of equipment closeups, shows stage set-ups, and includes “birds-eye-view” drone footage of the scenic range.

We like the swivel (“S”) version of the Harris bipod. The swivel (actually tilting) capability of the bipod allows you to tilt (cant) your rifle around the bore axis to level the rifle on a side slope or uneven ground. Unfortunately, the swivel tensioner (friction knob) that comes standard with a Harris swivel bipod leaves much to be desired. The tensioning knob is hard to adjust with your fingers. The small knurled ring doesn’t offer enough leverage. When it’s tight enough to prevent movement it’s hard to release. For this reason, many folks replace the standard knurled ring with a rotating adjustment lever with push-button release. This works great and is easy to install.
While you can buy levers from various sources, EABCO.com has a tried-and-true system that works with both Harris and Caldwell XLA-S swivel bipods: “Our S-Lever Tension Lever is an economical replacement for the friction tensioning knob to give you much better control and leverage.” For just $16.95, Eabco.com delivers all the parts you need for the upgrade to your swivel bipod. Shown below are instructions for installing the EABCO S-Lever.
Today we feature a modern switch-barrel PRS chassis rifle set up for quick changes between 6mm Creedmoor and 6.5 Creedmoor barrels. The owner, Forum member Jeff Cosgrove (aka “Punkur67″) uses the 6 CM barrel for competition, favoring the reduced recoil over its 6.5 mm big brother. He does use the 6.5 CM barrel for practice (given its better barrel life). The 6.5 CM barrel also gives him the chance to shoot a variety of factory 6.5 Creedmoor ammo.
- Terminus Zeus action with Quick Change (QC) barrel option.
– 6mm Creedmoor Pre-Fit Bartlein Heavy Varmint 400MODBB barrel for matches
– 6.5 Creedmoor Pre-Fit Benchmark Heavy Palma barrel for training
– MPA BA Competition chassis with full weight kit
– Zero Compromise Optic ZCO 5-27x56mm FFP scope
– TriggerTech Diamond trigger
This rifle represents an evolution for Jeff. Each step along the way in his PRS journey, he has learned more about what he wants and needs in a competition rifle. And what you see here, from the $3760 ZC527 scope to his high-tech reloading equipment, represents pursuit of excellence. Jeff even created a modern, spacious man cave/reloading center in his new house (photos below).
Quick-Change Barrel System with Terminus Zeus QC Action
This rifle has two pre-fit barrels that work with the Terminus Zeus QC Action for fast and easy barrel swaps. To remove a barrel, you simply release two tension screws on the front of the action and then unscrew the barrel. To swap in a different pre-fit barrel, reverse the process and then tension the screws. The Terminus Zeus is 3-lug receiver with 60° bolt and integral recoil lug. Both the receiver and bolt are DLC-treated. Jeff reports this action is extremely smooth and has met all of his expectations. Some other Zeus features are threaded trigger pins for quick/easy trigger installation, and a roller-tipped cocking piece.
PRS Discipline Offers Fun, New Challenge for Long-Time Shooter
My name is Jeff Cosgrove, I live in Winchester, California and do commercial heating and air conditioning. I have shot for 20+ years but I found my interest in shooting was dwindling over time. I got somewhat bored with shooting paper at 100 yards or plinking cans out in the desert. About 18 months ago I decided I wanted to shoot long range. I picked up a used MPA in .300 Winchester Magnum and started shooting long range with a new buddy. That day I fell in love with guns all over again with more intensity than ever.
How I Got Started in PRS
With that new .300 WM I soon found my reloads were not up to my expectations (high ES/SD), so I purchased all new reloading hardware. One of my purchases was a used Benchsource Annealer. The guy I bought that from asked if I had ever tried PRS and he invited me to check out a match. So I went to a local PRS event as a spectator. I looked at many rigs on the firing line and took notes. By the end of the day I knew this was something I really wanted to do. I then acquired a used chassis rifle that I thought would work well for PRS. I went to a PRS match the following month but shot poorly.
After working with that first PRS rifle, a 6.5 CM with Stiller Tac30 action, MDT chassis, and Proof Carbon-wrapped barrel, I quickly learned that gun did not handle and balance the way I hoped.* It was too light in the front, the ergos were poor, and scope eye relief was not optimal. So I decided to build my own GEN 2 PRS rifle. This is the story of how I put together my new switch-barrel rig that I now use in competition.
PRS Rifle and Gear Selection — Learning What Works
Barrel availability was limited given the current shortages. Luckily I was able to obtain a 6mm Creedmoor pre-fit Bartlein Heavy Varmint 400MODBB from Southern Precision Rifles. The 6mm Creedmoor is notorious for being a barrel burner cartridge so I went with the special 400MODBB metal. Bartlein says that barrel life expectancy is 1.5 to 2 times longer than the standard 416 grade steel. I also purchased a 6.5 Creedmoor pre-fit Benchmark Heavy Palma barrel for training (Source: Straight Jacket Armory). With the Terminus Zeus quick change system I am able to swap from my match barrel to my trainer barrel in just a couple minutes. I loosen two set screws, unthread the barrel, thread the new barrel on, and torque the set screws to 10 inch-pounds. This also affords me caliber options in case I’m in a pinch for ammo. If I have some 6.5 CM loaded up and don’t have time to load 6mm Creedmoor for a match, then I’m covered.
For the trigger, I went with a TriggerTech Diamond Pro curve model. I have Timney, Jewell, and TriggerTech triggers in other rifles. I like them all but I liked the feel of the TT Diamond the best so that is what I used on this build. I set my triggers around 18-20 oz. — I am not a fan of ultra-light trigger pulls.
MPA BA Competition Chassis with Added Weight
I went with an MPA BA Comp chassis with full internal and external weight kit. I also have Gray Ops external weight on the handguard. I had the same chassis on my .300 WinMag and felt very comfortable with it. I took a PR1 class and found that, with a different gun, I had to force a comfortable hand position for proper trigger pull. After that class I grabbed my MPA and my hand fell in to the perfect position. I did not need to hunt or index my hand with the MPA. The built ARCA rail (RAT) lowered the rifles center of gravity more than my old setup with the ARCA rail bolted to the bottom of the handguard. With the current configuration, the rifle weighs in at 24 lbs. and balances three inches in front of the magwell. I now have the flexibility to add, subtract, or move approximately 6 lbs. of weight.
The Attraction of PRS/NRL Practical Competitions
I really enjoy PRS-style shooting because there seems to be a new challenge every time you compete — no matter what. With PRS I am shooting many different positions and ranges with the pressure of a stopwatch. This keeps things interesting for me. I have taken a few training classes to help establish good, clean fundamentals.
Jeff says it is hard to practice for the many unconventional shooting positions at PRS matches.
My biggest challenges so far have been: 1) building stable shooting positions that I have not practiced enough; 2) proper equipment selection; and 3) time management. Regarding the shooting positions — PRS/NRL is not like F-Class where you can always practice from one position. And it’s hard to practice for unusual set-ups (barriers and positions) you’ve not encountered before. Concerning equipment — you need some experience in the game to determine what really works best for you.
Innovative Zero Compromise Optic — Optimized for the Tactical Game
The scope is a Zero Compromise ZC527 (5-27x56mm FFP) with MPCT2 reticle. Zero Compromise Optic is a relatively new manufacturer, but their scopes are top-flight. The First Focal Plane ZCO has excellent glass that is extremely bright and clear. With a big 36mm main tube, the ZC527 offers 35 Mils Elevation and 21 Mils Windage adjustment. The field of view is 21 feet at 100 yards — one of the widest in the industry. The ZC527 also offers illuminated reticle and locking turrets. When I was at my first PRS match I looked through several different scopes. When I got behind a ZCO scope I knew this was what I wanted — the ZCO scope was super clear, super sharp, with very positive controls.
I put a protective wrap on the scope because with some of our PRS stages it is easy to scratch or dent the scope tube. You don’t want to bang up an expensive scope — the ZC527 retails for $3760.
Reloading for 6mm Creedmoor and 6.5 Creedmoor
When starting out with a new cartridge I like to search places like AccurateShooter.com and UltimateReloder.com for popular recipes used by knowledgeable shooters. I am all about paving your own way on certain things but with the consistency, higher cost, and limited supply of components these days I try to stick with the most common loads. I also want to limit barrel wear and get through load development quickly. I don’t want to chase loads for 300 rounds to ultimately land in the same place that so many other people have already found.
I start my new barrels with virgin brass and load three rounds at each charge weight in 0.2 grain increments. I put the most popular charge weight (for my chosen bullet) in the middle of my load range and load above and below to find a good node while paying close attention for pressure signs along the way. I use the 6.5 Guys spreadsheet (see below) to help analyze my results. With those results I like to re-test a narrower range with 5-10 rounds each charge weight in 0.2 grain increments. I again use the 6.5 Guys spreadsheet to make a final charge weight selection and then I move on to seating depth. I will load different depths to tighten the groups up.
Load Development Using 6.5 Guys Custom Spreadsheet
To hold and analyze my load development data I use the spreadsheet from 65Guys.com. It helps a ton with making a decision on your final load. This Excel spreadsheet works great and makes it simple to analyze your data. You can even copy and paste your chronograph data if your chrono logs on to a SD card.
In this 6.5 Guys video Steve provides an overview and tutorial for using the Excel load development analysis model that he has developed. The Excel Load Development Analysis Spreadsheet version 2.0 is FREE. Download from the 6.5 Guys Website.
In this video Steve explains some key statistical concepts for performing load data analysis. He also provides tips and guidance for determining the optimal load for your rifle as you analyze the load data you’ve collected.
New House, New Man Cave/Reloading Room
Jeff recently moved with his family into a great new house. One bonus of this move was that he upgraded from a cramped reloading area to a dedicated “Man Cave” that has ample space for his gun safes, multiple presses, and all his reloading components. Large upper and lower cabinets plus a dedicated “gun closet” provide plenty of storage. Read all about this move in this AccurateShooter Forum Thread.
Here is Jeff’s first reloading area years ago: “My first reloading setup was smashed in my two-bedroom condo so I had a very small bench that was very cluttered. I had to deal with the limited space I had but I made it work. Then in our first house I had a larger bench/cabinet, but it was still not ideal.”
Here is the new Man Cave in the new house — very open, spacious, with plenty of storage.
This animated GIF shows the new Man Cave move-in process start to finish:
About Jerry Miculek… The Man, The Myth, The Legend
The video above begins: “My name is Jerry Miculek. Guns are what I do.” Jerry Miculek is a true legend in the firearms community. Acknowledged as the best wheelgun speed-shooter in history, Jerry is also an accomplished rifle and shotgun shooter with many class victories in 3-Gun competition. He also has been a prolific YouTube Video creator. For this Saturday at the Movies story, we are featuring five notable Jerry Miculek videos. You will find over 200 more informative and entertaining videos on the Jerry Miculek Pro Shooter YouTube channel
Here Jerry shoots two, double-barrel .45 ACP 1911 pistols (AF2011) at the same time, one in each hand. Jerry was the first-ever person to accomplished this 4-barrel feat with twin handguns. Employing the dual double-barreled pistols, Jerry send 20 rounds downrange in under 1.5 seconds. This amazing sequence is captured with hi-speed cameras for vivid slow-motion playback. There are some spectacular close-ups as the bullets leave the muzzles. Worth watching!
2. Take-Down and Full Cleaning of AR-15
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. In this video, Jerry Miculek takes down and cleans an AR-platform rifle belonging to his daughter Lena. This is a good video because Lena’s rifle was “run hard and packed up dirty” so you can see where carbon and grease build up. This 35-minute video is very thorough. Jerry is one of the nation’s top action carbine shooters, so listen carefully to his advice on cleaning and lubrication.
3. Jerry Reviews Magnetospeed T1000 Target Impact Indicator
MagnetoSpeed makes more than barrel-mounted chronographs. The T1000 is a target hit indicator that illuminates a super-bright red light when you hit a steel target. The T1000 was designed to be mounted to the back side of AR500 steel targets. In this video Jerry tests the MagnetoSpeed T1000 indicator light system. We like the T1000, especially for longer ranges where impacts on plates may not be easily visible. And you never have to paint your steel targets again to show impacts!
4. Shooting 240 Yards with 85-Year-Old K-22 Rimfire Revolver
Jerry Miculek is probably the greatest (certainly speediest) revolver shooter in history. He has set multiple world records with Smith & Wesson wheelguns. Here he tests a true classic — an 85-year-old S&W model K-22 revolver chambered for the .22 LR rimfire cartridge. Jerry uses this handsome classic blued revolver to hit targets at 240 yards!
5. 80,000 Philippine M1 Garands in One Place
Last year Jerry Miculek recently the CMP where he looked at the vast inventory of military rifles, including 80,000+ M1 Garands recently received from the Philippines. CMP tech staff showed Jerry some rare Garands that had never been issued. If you’re interested in classic military arms, you should definitely watch Jerry’s video. Gina Johnson, CMP’s general manager, told Guns.com that: “We have roughly 86,000 rifles from the Philippines and roughly 13,000 rifles from Turkey in our possession”.
Along with the 80,000+ Philippines Garands, the CMP received 13,000 from Turkey. The arrival of these 99,000 M1 Garands is great news for rifle collectors. Garands have been in short supply in recent years. Garands were getting harder to acquire from the CMP. In fact, over the past two years, many common Garand varients have been “sold out” on the CMP site.
A Clean AR is a Happy AR — Whether You Run ‘Wet’ or ‘Dry’
Doug Koenig took first place in the Production Division shooting Hornady 6mm 110gr A-Tip® bullets. Koenig noted: “This match is one of the toughest in the country and on day one, we experienced 35 mph winds. I am unbelievably impressed with how well the A-Tip bullets handle wind.”
