AR-platform rifles can be maintenance-intensive beasts. They need regular inspection, cleaning, and lubrication. 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, bolt carrier, and upper receiver internals will be less of a burden.
Here we showcase videos that show how to field-strip an AR-15, inspect the key parts, clean components, and lubricate internal parts as needed. Along with these videos, we recommend you read the comprehensive AR-15 Gun Cleaning Clinic article on the Brownells website. This explains in detail important procedures that the videos might only cover in a few seconds.
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here are five videos that explain how to properly disassemble and clean AR-platform rifles.
1. How To Clean Your AR-15 | Cleaning and Maintenance Tips
This is a quick 90-second starter video that may help new AR owners. Ricky Lehnhardt of OTIS Technology demonstrates the basics of cleaning and maintaining your AR-15. Lehnhardt does a good job identifying the points that need cleaning on the inside of ARs. However he works very quickly in the video. You may want to pause the video at some points. Also, Lehnhardt employs a cable for pulling patches and brushes through the barrel. Yes this is fast and easy. However, for match AR rifles, we recommend that you instead use a cleaning ROD with fitted bore guide.
2. Take-Down and Full Cleaning of AR-15 by Jerry Miculek
Here ace shooter 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. AR-15 Maintenance: Field-strip, Clean and Lubricate an AR-15
Gunsite Academy instructor and gunsmith Cory Trapp demonstrates the proper way to field-strip, clean, and lubricate an AR-15 carbine. In this 30-minute video, Trapp offers several important technical tips and hints. For example, at 11:05 Trap demonstrates how to determine if your bolt needs new gas rings. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.
4. AR-15 Dissassembly and Cleaning Guide
This video does a good job, with close-ups, showing how to remove the bolt carrier and clean the inside of the upper receiver. Then you can see how to work with various tools to clean the bolt, bolt carrier, and inside of chamber. We also recommend that you inspect the ejector recess and extractor recess. When we’ve inspected ARs that failed to cycle properly, we have often found nasty gunk (mixture of carbon, greasy lube, and brass particles) in these areas.
5. Basic AR-15 Quick and Easy Field Maintenance
In this NSSF-sponsored video, pro shooter Ryan Muller demonstrates basic, quick field maintenance of his AR-15. This would be for a quick cleaning and lubrication of the reciprocating parts. This covers rapid maintenance in the field. For full field-stripping and thorough cleaning, watch the previous videos.
Handy Mat for Cleaning AR Rifles
When working on an AR-15, it’s smart to have a pad that can absorb solvents and cushion your upper and lower. The $22.49 Real Avid Smart Mat is a good choice. This features printed take-down instructions and it has a handy parts tray on the right side. The mat rolls up for convenient storage. Click HERE to learn more.
Vital Inspections You Should Do After Disassembly
Last but not least, here are recommended inspections you should do every time you do a full field-strip and cleaning of your black rifle:

Earlier this week, U.S. House of Representatives passed a sweeping gun-control package titled the “Protecting Our Kids Act” (POKA). This radical legislation involves eight new statutes, covered below. Voting primarily on party lines, the Democratic-majority House approved the eight measures that collectively comprise POKA by a 223-204 vote.
NOTE: No part of POKA has become actual Federal law yet — it has only made it through the Democratic-controlled U.S. House of Representatives. For any part of POKA to become law, the provisions must be approved by the U.S. Senate and then signed by President Biden.
Here Are Key Statutory Components of the New POKA Federal Legislation:
1. Anthony Brown’s Raise the Age Act — This raises the lawful age to purchase a semi-automatic rifle from 18 to 21 years old.
2. David Cicilline’s Untraceable Firearms Act — This makes so-called “ghost guns” subject to existing federal firearms regulations.
3. Ted Deutch’s Keep Americans Safe Act — This is a new Full-Capacity Mag ban that would ban the sale, manufacture, and possession of New gun magazines that hold more than 15 rounds.
4. Robin Kelly’s Prevent Gun Trafficking Act — This creates new federal offenses for gun trafficking and straw purchasing.
5. Dina Titus’s End Bump Stock Loophole Act — This carries the Biden Executive orders further, by banning the manufacture, sale, or possession of Civilian bump stocks.
6-8. Gun Storage Regulations — There are three Gun storage proposals which mandate gun storage: Rosa DeLauro’s Ethan’s Law, Elissa Slotkin’s Safe Guns, Safe Kids Act, and Sheila Jackson Lee’s Firearm Safe Storage Act.
According to GunsAmerica Digest: “Only two Democrats — Reps. Jared Golden of Maine and Kurt Schrader of Oregon — voted against [POKA] while five Republicans — Reps. Anthony Gonzalez of Ohio, Fred Upton of Michigan, Brian Fitzpatrick of Pennsylvania, Adam Kinzinger of Illinois, and Chris Jacobs of New York — voted for it.”
The National Shooting Sports Foundation (NSSF) criticized lawmakers for supporting measures that clearly violated the Second Amendment rights of law-abiding citizens. The NSSF stated that POKA is seriously flawed, and violates the U.S. Constitution:
“This legislation isn’t a serious attempt to find common ground and effective answers. This was nothing short of a partisan effort to advance a radical gun control agenda”, said Mark Oliva, NSSF’s Managing Director of Public Affairs in a message to GunsAmerica.
“Many of the ideas included in this legislative package are unconstitutional, including denying Second Amendment rights to adults under the age of 21″, he continued. “The U.S. Court of Appeals for the Ninth Circuit just struck down California’s age-based gun ban as unconstitutional.”
Here is the analysis of the new POKA legislation from the NRA Institute for Legislative Action (NRA-ILA):
Among its many provisions, H.R. 7910 would ban law-abiding 18-20 year old adults from acquiring semi-automatic rifles and shotguns. This unconstitutional legislation would extinguish law-abiding adults’ Second Amendment rights and contends that these individuals are responsible enough to defend their country or vote in an election, but cannot be trusted to follow the law.
H.R. 7910 would generally ban standard-capacity magazines that are overwhelmingly popular with law-abiding Americans for self-defense, as well as redirect federal tax dollars intended for law enforcement and other public safety programs to “buyback” existing lawfully-possessed magazines.
Furthermore, H.R. 7910 includes several “safe storage” mandates that would control how individual Americans keep firearms in their own homes. These provisions are in direct contravention to the U.S. Supreme Court decision in Heller that held mandatory storage provisions that prevent a law-abiding American from having ready access to a firearm for self-defense are unconstitutional.
- – – -
The second bill, H.R. 2377, is a combination of legislative proposals to create ‘red flag orders’ that allow for the confiscation of firearms without due process of law. The legislation would directly empower federal judges to nullify Second Amendment rights on a case-by-case basis and issue orders to seize firearms from the named individuals. It would also provide funding to encourage states and localities to pass and enforce laws allowing judges to issue orders to seize firearms.
H.R. 2377 would strip Second Amendment rights of individuals by confiscating firearms without constitutional due process by allowing courts to issue ex parte (meaning the accused is not present) firearm confiscation orders. A person could be forcibly disarmed of otherwise lawfully-possessed firearms before he or she had so much as an opportunity to contest the accusations – this would represent a clear denial of constitutional due process protections.
Moreover, H.R. 2377 would generally authorize indefinite firearm deprivations, giving courts options to issue orders without a time cap, or choose to allow for indefinite order renewals. This legislation treats the Second Amendment as a second-class, disfavored right and flies in the face of due process, the presumption of innocence and fundamental fairness.

Yet another .300 Blackout disaster. Unfortunately, that .300 Blackout cartridge can fit in a .223 Rem chamber. Shooting a .308-caliber bullet in .223 bore is a recipe for disaster.
The .300 AAC Blackout aka “300 BLK”, is a compact 30-caliber cartridge designed to work in AR-15 rifles. It has a shorter cartridge case to accommodate the bigger 30-caliber bullet while still fitting in a standard AR-15 magazine. Unfortunately, that’s the danger. A careless shooter can toss a .300 Blackout cartridge in with .223 Rem rounds without noting. And because the case-head size is the same as the .223 Rem (5.56×45) the rifle’s bolt assembly will happily chamber and fire the .300 BLK round. Problem is, that forces a .308 diameter bullet down an undersized .223-caliber bore. Not good!
This images were provided by Tactical Rifle Shooters on Facebook. The message was clear: “Don’t try to run 300 Blackout in your .223/5.56mm. It won’t end well. The problem is identical rifles and identical magazines but different calibers.”
Image from Accurate Shooter Forum. Cutaway shows the jammed .30-Cal bullet:
For those who MUST have a .300 Blackout, here are some things you can do:
1. Use different colored magazines for .300 Blackout vs. .223 Rem.
2. Fit all your uppers with caliber-labeled ejection port covers.
3. Mark .223 Rem upper handguards with the caliber in bright paint.
4. Mark all .300 BLK Rounds with heavy black marker.
Comments by Folks Who Viewed these .300 Blackout Disaster Photos:
“The .300 Blackout is simply a badly-designed round. A properly-designed round would have had a feature in the shape that would have prevented cross loading in the first place.” — D. Santiago
“I almost made that mistake… I had a magazine of 300 BLK inserted in my .223/5.56 all night. Fortunately, I never pulled the trigger. Once I realized the mistake, I almost got ill. [After that incident] I no longer own a 300 BLK.” — B. Welch
“Happened to me hog hunting from a helo. Gun exploded in my face.” — B. Hood
“Fire-forming projectiles [is] so wrong in centerfire!” — M. Stres
“Had some dude come into the store the other day wanting .300 Blackout ammo to shoot in his 5.56 AR. It took 15 minutes of explaining for him to understand you got to have a .300 Blackout Upper!” — R. Williams

Many of our readers use AR-type rifles for Service Rifle matches, varmint hunting, 3-Gun competition, or defensive use. AR-platform rifles can be configured in a multitude of ways to suit the application. But if you plan to put together your own purpose-built AR rifle, how do you get started?
For AR Do-It-Yourselfers, we suggest reading the late Glen Zediker’s book, the Competitive AR-15 Builders Guide. Following on Zediker’s The Competitive AR15: Ultimate Technical Guide, the Builders Guide provides step-by-step instructions that will help non-professional “home builders” assemble a competitive match or varmint rifle. This book isn’t for everyone — you need some basic gun assembly experience and an aptitude for tools. But the Competitive AR-15 Builders’ Guide provides a complete list of the tools you’ll need for the job, and Zediker outlines all the procedures to build an AR-15 from start to finish.
One of our Forum members who purchased the AR-15 Builders Guide confirms it is a great resource: “Much like any of the books Mr. Zediker puts out this one is well thought-out and is a no nonsense approach to AR building. I can not stress how helpful this book is from beginner to expert level.”
Along with assembly methods, this book covers parts selection and preparation, not just hammers and pins. Creedmoor Sports explains: “Knowing how to get what you want, and be happy with the result, is truly the focus of this book. Doing it yourself gives you a huge advantage. The build will honestly have been done right, and you’ll know it! Little problems will have been fixed, function and performance enhancements will have been made, and the result is you’ll have a custom-grade rifle without paying custom-builder prices.” Other good resources for AR projects is Gunsmithing the AR: The Bench Manual, and the Building Your AR from Scratch DVD.

Do you own or shoot an AR-platform “black rifle”? Then you know these rifles run dirty, and have some unusual maintenance requirements. On the other hand, the AR “Modern Sporting Rifle” is fun and versatile with a vast range of options among buttstocks, barrels, handguards, and grips. You can assemble a simple 16″ barrel .223 Rem rig for home defense, or build a long-barreled 6mm ARC rifle with bag-rider buttstock and high-magnification optic for long range target work. The choice is up to you.
To help with your black rifle journey, here are eight helpful videos from Brownells. These will help ensure your AR rifle cycles reliably and runs longer, with reduced wear. Brownells also explains how to choose the optimal barrel twist rate. CLICK HERE to order AR parts, accessories, and ammo from Brownells.
AR Bolt/Bolt Carrier Lubrication — Smarter Methods
This video shows the proper way to lubricate an AR-15 bolt-carrier assembly. The video identifies the key metal-on-metal friction points where you actually need lubrication: the rails on the underside of the carrier, shiny wear points on top, and just a dab on the cam pin. How much oil/lubricant should you use? The AR-15 is pretty forgiving on that point. Some spots work best with grease, others work best with a lighter oil. Just keep it out of the combustion areas. Those little holes in the carrier are gas vent holes, NOT oil holes!
AR Maintenance — General Cleaning Procedures
Let’s face it, ARs with the original gas system tend to run dirty. You’ll need to regularly clean the bolt carrier and bolt. In addition you should regularly clean the chamber area and the inside of the upper. Also make sure to clean the lower (see video 3:15) and ensure the trigger assembly is properly maintained. This video covers general cleaning and maintenance of AR-platform rifles. We highly recommend that all new AR owners watch this video. NOTE: When cleaning the bolt, don’t forget the extractor recess and ejector recess. The majority of ARs we’ve seen that did not function properly had gunk (lube, carbon, brass shavings) clogging these areas.
AR Barrel Twist Rates — What You Need to Know
AR barrels can be ordered with a variety of twist rates from 1:12″ to 1:7″. Basically, the longer/heavier the bullet you plan to shoot, the faster the twist rate you need. For example, Sierra recommends a 1:7″ twist rate for the 90gr SMK. A 1:12″ could work with the small lightweight bullets up to 55 grains. The 1:9″ barrel will stabilize the light and mid-weight bullets up to about 77 grains. We recommend a 1:8″ or 1:7″ twist rate for the best versatility. You’ll find a detailed discussion of AR twist rates on PewPewTactical.com.
How to Install an AR15 Trigger Assembly
One of the most common AR upgrades done by black rifle owners is swapping out the trigger for a better unit (perhaps a two-stage). Trigger replacements on ARs can be done fairly easily with basic tools. But there are some recommended procedures to ensure the trigger group swap goes easily. You’ll want to have a proper mount to secure the lower, and tools that fit the pin diameters on your lower.
Must-Have Spare Parts for AR-Platform Rifle
With 350,000 views, this is one of the most-watched AR videos on the Brownells YouTube Channel. Brownells Gun Techs Steve and Caleb list key spare parts AR owners should have. Top of the list are bolt gas rings, which wear out through normal use. Also you’ll want a spare extractor spring and pin, because these both can fail. The cotter pin and cam pin can break, but more often they get lost when the Bolt Carrier Group is disassembled for cleaning. Additionally, the large buffer springs wear out with time, so have a spare. Downstairs on the lower receiver, keep spare springs and detents for the pivot and takedown pins. Finally, if you’ve upgraded your trigger, keep the original one as a backup spare.
Checking Headspace on ARs
In this Tech Tip, Brownells gun tech Steve Ostrem walks users step-by-step through the process of checking headspace on their AR-15 rifles, both new and used. It is very important to have proper headspace to ensure proper feeding and extraction, and to ensure good brass longevity (with less risk of dangerous case separation). Starting at 2:10, this video explains how to check headspace with go/no-go gauges and maximum headspace gauge. Ostrem notes: “If you have an AR that closes on a no-go gauge, we recommend taking it to a gunsmith before heading to the range.”
Excessive headspace in AR platform rifles can lead to dangerous case separation.
Setting Up Gas Tube Systems
This Tech Tip examines AR-platform gas systems, and shows how to select the proper length gas tube, and how to configure multiple tube systems if you change your barrel to different lengths. This is worth watching for anyone re-barreling an AR.
Barrel Gas Block Alignment — Key to Reliable Cycling
In this video, Brownells gun tech Steve Ostrem explains surefire methods to align your gas block. The most common problem with AR builds is poor cycling, commonly caused by misalignment between the gas block and the barrel’s gas port.

Do you use an AR15 for service rifle, 3-Gun, or tactical competitions? Then you should consider dry-fire training. Many top competitors spend an hour (or more) dry-firing for every minute they shoot live cartridges in competition. The allows effective training without spending a fortune on live ammunition (which can run $1.00 per round or more).
There is a handy new system that resets the trigger on AR-platform rifles — the Mantis Blackbeard (see videos below). This permits you to make multiple successive shots without having to alter your grip and manually recycle the charging handle. This two-part system employs a replacement bolt carrier/bolt and replacement magazine. With these two components installed, your AR can automatically reset the trigger instantly after you pull the trigger. It works, it’s effective, and it’s affordable at $219.00 MSRP.
The Blackbeard system is used by the U.S. Marine Corps and U.S. Army (including Special Forces), so you know it works. During training the Mantis Blackbeard allows unlimited, repetitive Dry Firing without resetting the charging handle. That eliminates a tedious task that requires altering your hold on the rifle.

This next video, from the manufacturer Mantis, shows how to install the Mantis Blackbeard, how to set the zero, and how to operate the unit with your AR-platform rifle.
The easy-to-install-Mantis Blackbeard replaces your bolt carrier and magazine in less than a minute, allowing easy training transitions. The magazine battery pack is good for 100,000 shots per charge and the Blackbeard is rated to reset as quickly as 10 shots per second, allowing rapid fire training for 3-Gun and tactical competitions.

Americans love AR-platform rifles. However, they can be maintenance-intensive, as hot gasses are directed right back into the action to operate the bolt. Because ARs have a somewhat unique (and dirty) semi-auto operating system, we think all AR owners should learn how their rifles operate — from the inside out. This feature provides an “inside look” at the AR, with X-Ray and Cutaway views created through advanced 3D computer modeling.
AR15 Functions Revealed with 3D Computer Animation
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:
How AR-Platform Rifles Work — General Introduction
To help reader understand the general operation of AR-type rifles, this video shows the control functions of an AR and how the upper and lower sections work together.
Cutaway 3D Animation of AR15/M16 Action — Watch Video
Here is an excellent “cutaway” animation by Thomas Schwenke that shows how an AR-15 functions — how the entire loading cycle works from start to finish.
AR platform rifles are semi-automatics version of the M16. These feature distinctive upper and lower receivers which can be readily separated via front and rear pins. The upper includes the barrel, handguard, forward gas tube, and bolt assembly, while the lower contains grip, trigger group, fire selector, and mag well. In addition the lower is attached to the stock which encloses the buffer assembly.
The original ArmaLite AR-15 was a select-fire, air-cooled, gas-operated, magazine-fed rifle designed by American gun manufacturer ArmaLite in 1956. It was based on Armalite’s AR-10 rifle chambered for the 7.62×51 NATO (.308 Win). In 1959, ArmaLite sold its rights to the AR-10 and AR-15 to Colt. Some key modifications were made — most notably, the charging handle was re-located from under the carrying handle to the rear of the receiver. The redesigned rifle was adopted by the U.S. military as the M16 carbine, which went into production in March 1964.

AR-platform rifles can be maintenance-intensive beasts. They need regular inspection, cleaning, and lubrication. 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, bolt carrier, and upper receiver internals will be less of a burden.
Here we showcase videos that show how to field-strip an AR-15, inspect the key parts, clean components, and lubricate internal parts as needed. Along with these videos, we recommend you read a comprehensive AR-15 Gun Cleaning Clinic article on the Brownells website. This explains in detail important procedures that the videos might only cover in a few seconds.
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here are five videos that explain how to properly disassemble and clean AR-platform rifles.

Here ace shooter 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. AR-15 Maintenance: Field-strip, Clean and Lubricate an AR-15
Gunsite Academy instructor and gunsmith Cory Trapp demonstrates the proper way to field-strip, clean, and lubricate an AR-15 carbine. In this 30-minute video, Trapp offers several important technical tips and hints. For example, at 11:05 Trap demonstrates how to determine if your bolt needs new gas rings. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.
4. AR-15 Dissassembly and Cleaning Guide
This video does a good job, with close-ups, showing how to remove the bolt carrier and clean the inside of the upper receiver. Then you can see how to work with various tools to clean the bolt, bolt carrier, and inside of chamber. We also recommend that you inspect the ejector recess and extractor recess. When we’ve inspected ARs that failed to cycle properly, we have often found nasty gunk (mixture of carbon, greasy lube, and brass particles) in these areas.

In this NSSF-sponsored video, pro shooter Ryan Muller demonstrates basic, quick field maintenance of his AR-15. This would be for a quick cleaning and lubrication of the reciprocating parts. This covers rapid maintenance in the field. For full field-stripping and thorough cleaning, watch the previous videos.
Handy Mat for Cleaning AR Rifles
When working on an AR-15, it’s smart to have a pad that can absorb solvents and cushion your upper and lower. The $24.99 Real Avid Smart Mat is a good choice. This features printed take-down instructions and it has a handy parts tray on the right side. The mat rolls up for convenient storage. Click HERE to learn more.
Vital Inspections You Should Do After Disassembly
Last but not least, here are recommended inspections you should do every time you do a full field-strip and cleaning of your black rifle:

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.
