The AR Addiction — The Compulsion to Buy More Guns

Hoarding AccurateShooter Forum AR

Forum member Kevin (aka “N10Sivern”), revealed he needs some help with a compulsion — a compulsion to keep buying more and more guns and ammo. Particularly ARs, all shapes and sizes of ARs. Way too many ARs. You could say he has an ARdiction….

In a Forum Thread, Kevin posted: “I may need an intervention. Trying to clean my office and pulled this stuff out. I’m missing an AR10 lower somewhere and an AR15 upper. I’ll find them before the day is done. I have a big box full of parts as well, and 4 barrels still in the cardboard tubes. Sigh. This is gonna be a lot of Cerakoting for me.”

Another Forum member said: “For the love of God, man. Delete this thread lest you be accused of hoarding!”

Kevin replied: “I guess I am hoarding a little. But it’s good hoarding right?”

And then he posted this “Mail Call” photo:

Loading for the AR10 Using a Progressive Press

Lock and Load Gavin Gear Ultimate Reloader AR-10
Gavin Gear tests .308 Win ammo with his DPMS LR-308B, AR10-type rifle.

Our friend Gavin Gear of UltimateReloader.com owns a DPMS LR-308B, an AR10-type semi-auto rifle. Gavin finds that his DPMS has a healthy appetite for ammunition. So, he set up his Hornady Lock-N-Load progressive press to produce .308 Win ammo. This video shows the process of press set-up and operation, complete with Hornady’s automated Case Feeder and Bullet Feeder. Employing elevated rotary hoppers, the case feed and bullet feed systems really speed up production. The automated feeders allow the operator to produce cartridges without ever touching case or bullet with his hands.

If you need large quantities of .308 Win ammo for 3-Gun matches or tactical games, and if you value your time, a progressive press may be a wise investment. The progressive can load a complete round with every cycle of the press handle. With Case Feeder and Bullet Feeder in place, the Hornady L-N-L can easily crank out a new .308 round every 3-4 seconds (watch video at 5:25). Conservatively speaking, that’s 15 rounds per minute sustained production (and some guys can go even faster).

To learn more about the Hornady Lock-N-Load Progressive Press (with case/bullet feed options), and to see a list of the dies and accessories Gavin uses, click the link below:

Sunday GunDay: Original 1950s AR-10, Father of All ARs

Armalite AR10 AR-10 rifle army 7.62x51 .308

Today, AR-platform rifles are hugely popular. Dozens of manufacturers sell AR-type rifles, in a wide variety of configurations and calibers. But before there were M16s and AR-15s, ArmaLite produced a 7.62×51 caliber rifle, the AR-10. Yes before there were millions of 5.56 black rifles, there was a .30-caliber big brother with reddish-brown furniture. Invented by Eugene (‘Gene’) Stoner for the Armalite company in the late 1950s, this is the father of all of today’s AR-platform rifles. Way ahead of its time, this remarkable, select-fire battle rifle weighed just 7.25 pounds as first developed.

If you’re curious about the AR-10, in this video, Jerry Miculek puts an original 1957-vintage AR-10 through its paces on the range. This extremely rare, early-production rifle was provided by Mr. Reed Knight and the Institute of Military Technology. (The gun in the video was actually produced in the Netherlands under license, see video at 4:40.) This AR-10 is the direct ancestor of the AR-15, M16, and many of the modern sporting rifles that we use today.

The AR-10 was slim and light, weighing around 7 pounds. Some folks might argue that the original “old-school” AR-10 is actually better than some of today’s heavy, gadget-laden ARs. The AR-10’s charging “lever” was under the carry handle — that made it easier to manipulate with the gun raised in a firing position.

AR-10 Armalite Jerry Miculek

You’ll notice there is no “forward assist”. Inventor Gene Stoner did not believe a separate “bolt-pusher” was necessary. The forward assist was added to solve problems encountered in Viet Nam. Some critics say the forward assist “only takes a small problem and makes it a big problem.” For today’s competition ARs (that are never dragged through the mud) the forward assist probably is superfluous. It is rarely if ever needed.

AR-10 Armalite Jerry Miculek

Note also that the handguards are fairly slim and tapered. Today, six decades after the first AR-10 prototypes, we are now seeing these kind of slim handguards (made from aluminum or lightweight composites) used on “full race” ARs campaigned in 3-gun competition.

History of the AR-10
The AR-10 is a 7.62 mm battle rifle developed by Eugene Stoner in the late 1950s at ArmaLite, then a division of the Fairchild Aircraft Corporation. When first introduced in 1956, the AR-10 used an innovative straight-line barrel/stock design with phenolic composite and forged alloy parts resulting in a small arm significantly easier to control in automatic fire and over one pound lighter than other infantry rifles of the day. Over its production life, the original AR-10 was built in relatively small numbers, with fewer than 9,900 rifles assembled.

In 1957, the basic AR-10 design was substantially modified by ArmaLite to accommodate the .223 Remington cartridge, and given the designation AR-15. ArmaLite licensed the AR-10 and AR-15 designs to Colt Firearms. The AR-15 eventually became the M16 rifle.

AR-10 3D Model Shows Internal Parts
If you want to see more close-up details of the AR-10, computer artist Stefan Engdahl has created a very detailed 3D model of the AR-10 for use in computer simulations. This computer model features 18 separate objects so you can look at details of frame, barrel, trigger, sights and more.

Here are some additional images of early AR-10 models, with various configurations. Multiple handguard and muzzle options were employed during early development.

Zediker Examines Long Range Shooting with AR-Platform Rifles

AR15 ar-15 long range

Looking to shoot an AR-platform rifle out past 500 yards? Then you should read two articles by AR guru Glen Zediker. Author of The New Competitive AR-15 and The Competitive AR15 Builders Guide, Zediker is an expert when it comes to AR-platform rifles. Glen believes ARs have excellent long-range capability, provided they are built to high standards, with good barrels.

Glen says: “a properly configured AR-15 is easily capable of good performance at 500+ yards. Good performance means it can hit a 1-foot-square target all the time. Competitive shooters can cut that standard in nearly half (the X-Ring on an MR1 600-yard NRA High Power Rifle target is 6 inches, and high X-counts are commonplace among more skilled shooters).”

Published in the Cheaper than Dirt Shooter’s Log, Zediker’s articles first cover the history of the AR-15, and then explain how AR-platform accuracy can be optimized. Part One reviews the AR’s development as an accurate firearm, tracing its evolution from a Vietnam-era combat weapon to what is now a favored target rifle of High Power competitors. READ PART ONE.

Long Range AR AR-15 Glen Zediker Cheaper than dirt

Part Two discusses the specifics that make an AR accurate at 500 yards and beyond. Zediker talks about barrel configuration (profile and twist rate), bullet selection, floating handguards, and proper mounting of optics or iron sights. READ PART TWO.

Long Rang AR AR-15 Glen Zediker Cheaper than dirt

Here are some highlights from Long-Range AR-15 Part TWO:

Barrel Twist Rate
To stabilize anything longer than a 68- or 69-grain bullet, the barrel twist rate must be — at minimum– 1-in-8. Twist rates reflect how far the bullet travels along the lands or rifling to make one complete revolution. So, 1-in-8 (or 1-8, 1:8) means “one turn in eight inches.” I think it’s better to go a little faster in twist. There is nothing wrong with a 1:7 twist. The 90-grain bullets require a 1:6.5, and that is getting on the quick side. If you want to shoot Sierra 77s or equivalent, and certainly anything longer, 1:8 is necessary. By the way, it is bullet length, not weight, which constitutes the necessary twist rate to launch a stable bullet.

Optics Mounting
Correct optical sight positioning can be a challenge. With a flattop upper, I need a good inch additional forward extension at the muzzle side of the upper for the sight mount bases to avoid holding my head “back” to get the optimal view through the scope. A longer rail piece is necessary for my builds as a result.

Buttstock Length and Adjustment
An adjustable buttstock is valuable, and even more valuable if it’s well-designed. Mostly, a standard stock is too short, and the cheek area sits too low. Adding length helps a lot by itself. There are assemblies that replace the standard buttplate to allow for length and, usually, height and rotation adjustments for the buttpad. An elevation-adjustable cheekpiece is a big help to attain a solid position.

Sunday Gunday: AR-Platform Rifles for PRS Gas Gun Series

AR15 AR-15 Gas Gun Series

ARs in PRS? Yes PRS has a “Gas Gun” division. And frankly, shooting a PRS match is one of the most fun and challenging things you can do with your Black Rifle (Beto O’Rourke notwithstanding). Since the early days of the PRS, Gas Gun shooters have wanted to play. Recognizing the interest among semi-auto shooters, the PRS now offers a Gas Gun Series for semi-auto rifles such as AR15s and AR10s. The Gas Gun Series started in 2017, and has quickly become quite popular.

PRS Gas Gun Series Rules

For the new PRS “Gasser” Competition, the PRS developed rules on gun types, scoring, match timing, penalties, safety and other key topics. CLICK HERE for Full PRS Gas Gun Series Rules.

Open Division: Open Division rifles will not exceed a caliber of .30 or a velocity of 3,200fps. A match DQ will result any rounds over the speed limit of 3,200 fps (+/- 32 fps for environmental factors and equipment discrepancies). Match Officials may request at any point during a match that a competitor fire their rifle through chronograph. If the bullet exceeds the 3,200 fps speed limit, the shooter will receive an automatic match DQ. [“For Ammo in Open Class, 6mm and 6.5mm Creedmoor are popular.” — John Parker, SSUSA]

Tactical Division: Tactical Division: Intended to allow competitors the opportunity tocompete using traditional military and law enforcement caliber. This promotesActive Duty military and law enforcement competitors use of their Service and Department issued rifles. Tactical Light Division rifles are restricted to 5.56 NATO/.223 Remington and 7.62 NATO/.308 Winchester calibers only. .223 Bullet weight cannot exceed 77 grains and muzzle velocity cannot exceed 3,000 fps, .308 bullet weight cannot exceed 178 grains and muzzle velocity cannot exceed 2,800 fps. No modified wildcat rounds permitted to shoot in the Tactical Divisions. Tactical Division shooters will shoot the exact same COF as Open Division shooters. [NOTE: This division now replaces the previous Tactical Light and Tactical Heavy divisions.]

Scoring and Penalties
The Gas Gun Series utilizes a time plus penalty based scoring system for all match scoring. This means your score is your total combined time on all stages plus any penalties you may have accrued.

Stage Course of Fire and Targets
No more than 50% of the stages at a match can utilize an unlimited round count. At least 25% of the targets in Gas Gun Series match must be 2 MOA or smaller. Maximum distance is 800 yards.

The preferred rifle color choice at the first PRS “Gasser” Match was definitely black…
PRS Gas Gun

Gas Gun Match Loads — Short Range vs. Long Range
“The .223/5.56 [Tactical Light] guns had some lag time waiting on shot impacts. I believe the long-term solution may be to find a light and fast load for closer stages for near-instant reaction time and use a heavy load for the long shots to see splash and get the target to move a little more.” — Sean Murphy, Nightforce

Gear Options for PRS Gas Guns
There are many buttstock options for ARs. For the PRS game, we like the Magpul PRS stock. This features a quick-adjustable cheek-piece and butt-plate — allowing you to easily adapt head position and LOP for your discipline of the day. (You may want a different LOP for prone shooting vs. bench shooting). The Magpul stock works well in a rear bag.

Colt AR AR15 match rifle upper lower kit discount CDNN

We recommend something like the Blackhawk grip which is more comfortable than the typical grips supplied by most black rifle makers. Up front, you’ll want a handguard with adaptability. Shown is a handguard with Picatinny rails on top and on both sides, affording lots of options. We might move one of the rails to the bottom, however, so it could be used for a bipod mount.

PRS with a Gas Gun — Gavin Gear’s Experience

Thinking of trying out the Precision Rifle Series, starting off with a gas gun? Well Gavin Gear of UltimateReloader.com did just that, competing in his first-ever PRS match up in Washington State. With its timed stages (some just 90 seconds long), Gavin learned that PRS is about speed as well as accuracy. As a PRS newbie, Gavin found the competition fun but challenging. Gavin’s account of his experiences, set forth in two articles with accompanying videos, will help other novice PRS competitors prepare for PRS-type matches and assemble the right equipment.

This video has cool Aerial Drone footage, and in-depth explanation of stages:

READ Full Story of Gavin’s First PRS Match »

Gavin enjoyed his first match: “Overall, the match was more fun and more laid back than I thought it would be. The guys in our squad were all really helpful, and even loaned me gear to try out when they noticed my gear wasn’t right for a particular shooting activity. One such case was when Ken Gustafson (of KYL Gear) offered to loan me one of the bags he had made. Below you can see me shooting off the infamous unstable tippy tank trap with a KYL Gear bag, and I’ll have to say [the bag] was amazing. It helped me lock down my rifle and get on target. What a great feeling!”

Black Rifle Trigger Fest — AR15 and AR10 Triggers Reviewed

AR15 AR10 Trigger Geissele Timney Elftmann 2-stage ALG Defense modularTrigger images from PrimaryArms.com, which sells all the triggers reviewed here: Geissele, Elftmann, Timney, and ALG Defense.

Are you thinking of upgrading the trigger system for your AR-platform rifle? There are dozens of options available, from $45 up to $300. Thankfully, Brownells has created video reviews of some of the more popular AR trigger options from Timney, Geissele, and ALG Defense. And we included a video review of the highly-regarded Elftmann Match Trigger. If you want the best solution for Service Rifle competition, you might favor the Geissele. For ease of installation, it’s hard to beat the Timney, a “drop-in” module. Like the Timney, the super-smooth Elftman is a drop-in module. At $249.00 it’s pricey, but it is one of the best AR triggers out there. If you’re on a tight budget, the best “bang for your buck” may be the “Perfected Mil-Spec” ALG which starts at around $45.00.

Multiple AR Triggers, including the Elftmann and Geissele, Are Reviewed in this Video

Though pricey ($249.00 at PrimaryArms.com), we really like the Elftmann AR trigger. It combines the best of both worlds — the precision and smoothness of the Geissele with the Timney’s ease of installation. This single stage trigger is user-adjustable from 2.75 to 4 pounds pull weight. It is offered with either straight or curved trigger blade. Primary Arms says: “The amazingly short take-up, glass-rod crisp break and [near-zero] over-travel can be compared to the finest custom 1911 triggers.”

Geissele Enhanced Two-Stage Trigger

Geissele makes a variety of quality AR trigger sets both single-stage and two-stage. Many High Power competitors like the two-stage Geissele trigger. This delivers a repeatable, controlled pull through the first stage with a very clean break in the second stage. The Super Dynamic Enhanced Trigger, shown above, features a distinctive, trigger blade. Reviewer Thomas Conroy says: “The flat surface is very easy to press against. Both stages are light and very distinct.”

Timney Drop-In Trigger Module

This trigger module is available for both the AR15 and the AR10 platform (see above video). Timney triggers are easy to install and come with multiple pin size and pull-weight options. Reviewer Thomas Conroy confirms that the single-stage Timney “breaks cleanly and crisply. This trigger is modular, meaning that the trigger, sear, hammer, and spring are all encased in a bright, shiny yellow aluminum housing.”

ALG Defense Trigger — Higher-Quality Basic AR Trigger

According to Thomas Conroy, ALG triggers “are the perfected version of the standard, non-adjustable mil-spec original trigger. They have the same geometry, but are made to higher quality standards, and come with … hardened and smoothed-out sear contact surface to eliminate all grittiness.” These are also offered in a nickle-boron coated version. Available for under $45.00, the ALG is a well-made, low-cost option for shooters who want a better factory-type trigger system.

X-Ray Views Show How Rem 700 and AR Actions Work

3d firearms modeling gun CGI software encylopedia gun disassembly

Ever wish you could look inside your rifle, to see how the trigger and fire-control system work? Well now that is possible with the magic of 3D computer graphics. Modern software allows detailed “cutaway” side-views (see below), as well as 3D views with 360° rotation. The software can also provide X-Ray-type views into the gun’s internals — as you can see above. And computer animation can show the complete firing process from trigger pull to chambering of the next round.

Rem 700 Cutaway View from Right Side
3d firearms modeling gun CGI software encylopedia gun disassembly

This article covers two different animations — a bolt-action, and a self-loading “gas gun”. The first video features the popular Rem 700 action, probably the most successful American bolt-action ever created. The second video offers a lengthy exploration of the AR15/M16 platform.

READERS — Take the time to watch these videos! The Rem 700 animation is really outstanding! EVERY bolt-action shooter should watch this video all the way through.

Cutaway 3D Animation of Rem 700 Action — Watch Video

The Model 700 series of bolt-action rifles have been manufactured by Remington Arms since 1962. All are based on basically the same centerfire bolt action. They are typically sold with an internal magazine depending on caliber, some of which have a floor-plate for quick-unloading, and some of which are “blind” (no floor-plate). The rifle can also be ordered with a detachable box magazine. The Model 700 is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948.

3d firearms modeling gun CGI software encylopedia gun disassembly

The Rem 700 is a manually-operated bolt action with forward, dual opposed lugs. It features “Cock On Opening”, meaning the upward rotation of the bolt when the rifle is opened cocks the firing pin. A cam mechanism pushes the firing pin’s cocking piece backward. The bolt face is recessed, fully enclosing the base of the cartridge. The extractor is a C-clip sitting within the bolt face. The ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together (head, body. and bolt handle). The receiver is milled from round cross-section steel.

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.

2. Fort Benning Multi-Gun Challenge. This is one of the best 3-Gun events of the year. If you like fast action, with rifles, pistols, and shotguns, you’ll love this Shooting USA sequence. The U.S. Army Marksmanship Unit at Fort Benning, Georgia hosts one of the toughest and most challenging multi-gun matches. Watch top competitors move through difficult stages that test strength and agility as well as marksmanship.

Multi-gun competition tests shooters’ skills with rifle, pistol, and shotgun, running stages “on the clock”. You must be fast AND accurate to successfully complete a course of fire.

3. Classic Arms — The U.S. Army’s Model of 1917 Rifle. The Model 1903 Springfield is perhaps more famous, but more Model 1917 rifles were actually issued to American troops in World War I. This sequence covers the history of this important American battle rifle.

4. Rimfire Challenge World Championship (RCWC). This is a great family event. The Rimfire Challenge is a timed, short-range event for .22 LR handguns and rifles. In recent years, the RCWC has been held in Alabama with 16 stages, 8 for rifle and 8 for pistol. This major match attracts hundreds of competitors from around the nation. It’s fast and fun with instant feedback from ringing steel plates. The RCWC is family-friendly event that’s great for all skill/experience levels.
