 What happens when a round goes off unsafely in an AR? Watch this video and see. At about the 00:40 time-mark the shooter has a malfunction (click no bang), with a round. He then removes the magazine, and clears the chamber (we think). On the next round, at 00:53 you hear a “Bang” and see a big puff of smoke coming out of the upper receiver (see photo at right). This has been called a “detonation” by the video-maker, but we’re not 100% sure what happened. What do you guys think? Watch the video carefully, and state your conclusions in the comment section if you wish.
What Caused this Malfunction? Watch Video…
In any event, the shooter is fortunate his upper did not completely fracture, launching shrapnel into his face or other body parts. This could have turned out much worse. Here are screen-shots from the video, showing details of the gun after the accident, along with the recovered brass case, which separated near the case-head.

 AR this, AR that… sometimes it seems the gun world has gone AR crazy. There is even a book specifically dedicated to reloading for AR-platform rifles. This may seem superfluous when there are so many other reloading manuals on the market. However, there are some special factors to consider when reloading for ARs and other semi-automatic rifles. Cases should be full-length sized, with adequate shoulder bump and neck clearance (more than you might run with a bolt gun). Cartridge pressures must be appropriate for the AR platform, and you want to select powders that minimize fouling. Also, when loading for an AR you may want to experiment with cannelured bullets and crimping. And of course, rounds must be loaded to mag-length. Lastly, with the advent of the 300 AAC Blackout (and similar cartridges), many AR shooters now are experimenting with heavy 30-cal bullets in subsonic applications. AR owners will experience a “reloading learning curve” when moving from .223 Rem to the more exotic, subsonic 30-caliber cartridges.
These and other concerns are covered in Lyman’s new AR Reloading Handbook. This comprehensive reloading guide provides the AR shooter with reloading data for nearly all popular AR-platform chamberings. In addition to data for the standard .223 Rem, the following cartridges are also covered: 6.8 Rem, 300 AAC Blackout, 7.62×39, 450 Bushmaster, 50 Beowulf and others.
Lyman touts its new book: “Reloaders will appreciate the wealth of AR-specific reloading data [for] all popular brands of bullets and powders. Specialty cast bullet and sub-sonic data further expand the usefulness of the handbook. Interesting articles by well known and popular firearms journalists are also included. These cover such areas as ‘Reloading for Suppressors’ and ‘Cartridge Interchangeability”. Finally all this AR data is presented in a full size, easy-to-use 8 1/2″ x 11″ format.”

 Here’s a cool new optics mount at a very attractive price — just $87.95. Midsouth Shooter’s Supply is now featuring the Warne Skeletonized integrated scope mount for Picatinny Rails. This should work great on flat-top ARs. And for you fashionistas out there, the Warne mount is offered in four different colors: Matte Black, Dark Earth (tan), Ruby Red, and Bold Blue. Tactical shooters will probably pick black or tan sets, while image-conscious 3-Gun competitors might favor the Red or Blue versions.
These Warne integrated ring/mount sets are offered for 1″, 30mm, and 34mm rings. The 1″ and 30mm versions come in all four (4) colors and cost $87.95. The 34mm is offered in Matte Black only for $115.00. You may want to order soon. These are popular. The most popular colors (black and dark earth) could sell out quickly at this price.

 Gun Digest will be producing a new quarterly print magazine, called Modern Shooter. It appears that the magazine focuses mostly on AR-platform rifles, AR accessories, and defensive shooting. The new magazine parallels the new Modern Shooter television show, which debuts on the Sportsman Channel next January. Look for Modern Shooter magazine on newsstands in April. The new magazine will also be available in digital format at www.gundigeststore.com.
Each issue of Modern Shooter will focus on a popular firearms category. For example, the premier issue explains how to maintain an AR rifle, and how to “Defend Your Castle” with an AR. This first issue features Richard Mann’s 12 training drills for AR-platform rifles, plus reviews of AR accessories: optics, sights, rails, and adjustable stocks. The premiere edition of Modern Shooter profiles Colt manufacturing, discussing the history of the company. Colt’s new LE6920MP-USA and AR15A4 rifles will be reviewed.

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).

Yep, if you buy a qualifying Nikon AR riflescope, you’ll receive the corresponding AR mount (retail value up to $99.95) for free. Included in the offer are Nikon’s P-22, P-223, and M-223 riflescopes. Nikon’s M-223 and P-223 scopes are built specifically for the .223 Remington cartridge. With BDC (bullet drop compensating) or Nikoplex reticles, they are designed to give AR shooters a high quality optic with fast sighting speed. The P-22 is the rimfire-optimized variant designed for the .22LR cartridge.
Choose Two-Piece or One-Piece AR-specific Scope Mounts
Nikon has developed two types of AR scope mounts for AR platform rifles. The new P-Series mount (shown above) is a two-piece design that can mount a P-22 or P-223 scope to almost any AR platform rifle. The M-223XR mount is a one-piece design made for the M-223 riflescope. The angled-base M-223XR offers +20 MOA of built-in elevation for long-range shooting.
The P-Series mount is available with the purchase of the following P-223 or P-22 scopes:
P-223 3×32 Carbine Reticle (#8496) | P-223 3-9×40 BDC 600 (#8497) | P-22 2-7×32 (#8498, #8499)

The new Micro-Sight was developed by scientists at Idaho National Laboratory (INL). This revolutionary optical insert for iron sights allows you to see BOTH the target and your front sight in sharp focus. The Micro-Sight employs Phased Zone Plate technology to improve focus of both close and distant objects.
 Creedmoor Sports Now Selling Production Micro-Sight
This summer we reported that the Micro-Sight was in development. Now Creedmoor Sports has the first-ever production Micro-Sight, a special hood for AR and service rifle rear sights. The Micro-Sight hood sold by Creedmoor replaces a standard AR-15 hood (1/4-32 threads) as found in most NM AR-15 rear sights. The Micro-Sight element is positioned in the center of the hood, where it is shielded from moisture and impacts. Licensed by INL, the new Micro-Sight for ARs will be followed in the spring by inserts for popular rear match sights. The new SR Micro-Sight insert for ARs, item MS-1, costs $139.95. Order soon — Creedmoor has sold nearly 100 sights in just two days! Click HERE or call 800-273-3366 to order.
The Micro-Sight really works, and it makes a huge difference, particular for “older eyes” that have trouble focusing on both the target and the front sight. For the first time you’ll have a sight picture where the front sight and the target are both in focus. Creedmoor’s Dennis DeMille, a former National Service Rifle Champion, tells us: “This is one of the most game-changing products to come out in years!”
WATCH the VIDEO below to see the Micro-Sight in Use and to learn how it works…

 Geissele triggers are highly regarded by high power and service rifle AR shooters. Now there is a new line of moderately-priced Geissele triggers, sold exclusively by MidwayUSA. Geissele will produce three types of Super-Dynamic triggers for MidwayUSA: Combat, Enhanced, and 3-Gun. These will all boast tool steel hammers and precise, Wire-EDM-cut sear surfaces. The 3-Gun model has a special “short reset” feature to allow quicker shot strings in competition. Unless you’re “running and gunning”, however, you’ll probably prefer the “Enhanced trigger”, which features a 2.2-lb first stage, a 1.2-lb second stage and crisper break.
 Geissele’s Super-Dynamic triggers feature a straight vertical trigger bow, preferred by many competitors. Geissele claims its HI-SPEED hammer cuts lock time by 50% compared to standard AR hammers.
The Combat Trigger features a 2.5 to 3-lb first stage and a 2-lb second stage. Normal price: $209.99.
The Enhanced Trigger has a 2.2-lb first stage, a 1.2-lb second stage and crisper break. Normal price: $224.99.
The 3-Gun Trigger was designed with input from competitive multi-gun shooters and features a “hybrid” 3.5-lb pull and shorter reset for rapid target engagement. Normal Price: $234.99.
ON SALE Through December 31, 2010
These three Geissele triggers are all marked down this month. The Combat trigger is reduced $21.00 to $188.99. The Enhanced trigger is discounted $25.00 to $199.99, and the 3-Gun trigger is marked down $25.00 to $209.99.
