Armalite AR10 Magazines

In a rare occurrence these days Armalite Ar10 magazines in various capacities have become available to purchase. Brownells currently has stock of Armalite AR10 magazines 10 5 round, 10 round, 20 round and the holy grail 25 round capacities. Click here and get them while you can. Hopefully this is a sign of the magazine shortage coming to an end.


Armalite has announced the release of the AR-10A. The AR-10A accepts the original preban AR-10 waffle magazines as well as 3rd party magazines such as the MAGPUL LR20 PMAG. For those who don’t know Armalite moved away from the original AR-10 waffle magazines during the federal assault weapons ban. At that time Armalite moved to the readily available M14  magazines that with a slight modification functioned in the AR-10B. Over the years Armalite derived their own magazines as well as modified that platform to better suit the now standard magazines.

Over the years shooters complained that if they wanted an AR-10 they had to settle on the proprietary  magazines which were expensive and only manufactured by Armalite. In 2009-2010 as more weapon manufacturers began to develop and manufacture 308 AR weapons almost all settled on the original Stoner design AR-10 magazine. Along the same time line Magpul Industries released the LR20 308 PMAG. The 308 PMAG became a game changer at under $20 and shooters would select other brands over Armalite simply for the ability to use PMAGS.

Well here in 2012 you can have the best of both worlds an AR-10 that accepts PMAGS.

This is one of my pet peeves. Guys go out and spend a $1000-$3500 of their hard earned cash getting their 308 AR just the way they like it. Then proceed to buy the cheapest possible ammunition they can find. Then they are surprised when the rifle wont function correctly.

Below is a scenario that plays out constantly in my inbox and forum.

Guy heads out to the range and is surprised when his shiny new rifle fails to function properly. He then bring the rifle home fiddle to with it, maybe get some opinions from friends or the internet and heads back to the range for more of the same. Inevitably either on his own or from gathering opinions the need to try an alternate ammunition become apparent. once again off to the range for more of the same. Now the shooter is angry that he spent all this money on a rifle that wont run. In anger he will call the weapon manufacturer tech support hotline. In most cases tech support will steer him to try a different magazine and maybe even another brand of ammunition. Back to the range and maybe the new magazine helped a little, small encouraging signs but the gun is basically a single shot. Back home and the shooter is livid back on the phone with the manufacturer for an RMA number. Two months later the gun will return with a note stating the chamber  was polished. Our excited shooter heads back to the range and the rifle still doesn’t function properly.

First off DPMS has gone so far as publish a list of AMMUNITION NOT TO USE IN ANY DPMS RIFLE INCLUDING THE LR-308.

Here is that list

Ammunition Warning

After extensive testing, we have found that only ammunition manufactured to SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications is reliable in DPMS rifles. DPMS recommends the use of high quality, domestically produced ammunition for best results and highest accuracy. For plinking and practice, we recommend only domestic, commercially manufactured ammunition. Please note: the use of hand-loaded ammunition voids the factory warranty. The use of all ammunition listed below also voids the warranty.

We have incurred feeding problems with the following:

    • Israeli ammunition
    • Korean ammunition
    • Chilean ammunition
    • Portugese ammunition
    • PMP
    • South African produced surplus
    • Lacquer Coated Ammunition or Steel-cased, lacquer coated ammunition
    • Wolf
    • Norinco
    • Silver Bear
    • Any steel-cased (coated or non-coated) ammunition
  1. We have reviewed several reports, from several manufacturers’, regarding problems using this ammunition. The problem appears to be the bullet contour and the overall length of the cartridge, which is contacting the rifling before firing. This is creating a gas port pressure and chamber pressure higher than recommended, therefore causing feeding and extraction problems due to the increased bolt carrier velocity. In addition, there is accelerated fatigue on internal parts. There are also indications that brass may be out of spec, which could create an unsafe condition.

    We have used this ammunition in the past for testing purposes and found the brass is extremely soft and can “flow” into microscopic pores and grooves in the chamber creating “sticky” extraction. This has been reported in many types of rifles, but is more prevalent in semi-automatic weapons.

    The problem with this ammunition is that the lacquer coating on the case. As the barrel heats up, the lacquer turns to a soft, varnish substance and upon cool down, becomes very solid and difficult to remove. This effectively creates an undersized chamber and creates understandable problems.

Your rifle is an investment and it only makes sense to choose quality ammunition for a quality rifle!

My Opinion

First off should you really be surprised when an ammunition that costs 1/4 to 1/2 the price of domestic ammunition fails to function properly in a weapon? I think not. Secondly you can swap one inferior brand for another and expect the same result.

What’s the point of shooting this ammunition other than cost? It’s not accurate despite most internet reports to the contrary. It’s not consistent from one lot to the next. So even if you manage to get a good batch it’s no guarantee the next lot will be any good. The ammunition is dirty as hell and possibly corrosive unless you believe the print on the box. You cant stake your life on it in a SHTF situation.


I’m not saying you  need to run out and buy Federal Gold Medal Match but you need to use some common sense. For cheap 308 ammunition look to one of the generic domestics such as Federal American Eagle or Winchester USA. If that’s still to pricey the PRVI PARTIZAN brand offers excellent value and accuracy. Avoid anything that has an animal in it’s name.

I think DPMS sums it up in one sentence. Your rifle is an investment and it only makes sense to choose quality ammunition for a quality rifle!

Advice for a 308 AR that wont cycle properly

If your 308 AR is DPMS compatible the simplest way to verify your 308 AR functions properly is to buy a MAGPUL 308 PMAG and few boxes of premium ammunition. The PMAG eliminates the possibility of a magazine issue as they are nearly perfect and the premium ammunition will be clean burning and accurate which will help you get that new 308 AR broken in and functioning like a champ. If you have an Armalite omit the magazine as there are no alternatives.

Note: A new 308 AR needs a lot more lubrication then an AR-15. Put some Mobil 1 on the bolt carrier and bolt ot maybe even your favorite gun grease on the bolt lugs. The BCG should be almost dripping wet with oil for the first few hundred rounds.


After only a few short weeks my of waiting the MEGA ARMS MA-TEN 308 AR RECEIVER SET arrived exactly as scheduled. My first impressions out of the box is very good. The units have been manufactured and finished flawlessly.  The MEGA ARMS MA-TEN 308 AR RECEIVER SET will be used in the #3 308 AR build project at 308AR.com.

AR 308 Tools

308 AR Tools:

AR-10 DPMS LR-308 SR-25 AR 308 Specific Tools

Much like their smaller AR15 siblings these large bore AR rifles require very specific tools. Additionally theres more information at my other sites on basic gunsmithing tools and AR15 tools.

AR 308 AR-10 Triggers



For the most part standard AR-15 triggers will work in the large frame .308 AR pattern rifles. There are however a few considerations to think about.

SAFETY: The first and foremost consideration is safety. While you may be inclined to go for the light pull weight your accustomed to in your bolt rifles that type of trigger is not advisable with these heavy recoiling rifles. A pull that is to light can possibly cause the gun to fire in uncontrolled full auto which will be dangerous to you the shooter as well as those around you. Guns designed for full automatic fire have their fire control system timed to fire at a predetermined rate with the gun not firing until the bolt is locked in firing position. Uncontrolled automatic fire can result with the gun firing without the bolt locked in place essentially possibly causing the gun to blow up in the shooters hands. The most common recommendation I read is not to go lower than 4# and if possible use a two stage trigger.

TRIGGER FIT – INSTALLATION: As I mentioned in the first sentence most aftermarket AR15 triggers will work in the .308. There is one caveat though. Some triggers will require modification or interference with the bolt carrier will result. So with that in mind I suggest sticking with triggers that are designed for the .308AR and designated to do so from the trigger manufacturer. If you are unsure call the trigger manufacturer or seek the help of a qualified gunsmith.

Brownells has recently added a dedicated section of triggers specified to work in the 308AR Rifles and AR-10’s

Geissele Automatics, LLC .308 AR AR-10 Trigger

Geiselle triggers are the standard by which all other triggers are judged with regards to AR-15’s as well as the .308 AR’s and AR-10’s

Geissele Automatics, LLC .308Ar,AR-10 Trigger

Fully adjustable trigger gives a smooth, two-stage pull with a precise “icicle sharp” break and ultra-fast lock time to minimize accuracy loss caused by gun movement during trigger pull. Set first stage pull weight by bending the legs of the trigger spring; set second-stage weight within a pre-set range by turning its adjustment screw. Another screw on the trigger lets you adjust over travel for clean, crisp let off. Lightweight hammer provides a 50% reduction in lock time over factory hammer, yet uses standard weight hammer spring to ensure sufficient energy transfer for reliable primer ignition, even on AR-style .308 weapons. Trigger shoe is positioned 1/8″ farther forward than factory shoe for comfortable finger position during the squeeze. All contact surfaces are wire EDM cut to exact dimensions for full, precise engagement free of unwanted play. Available to fit both large (.169″) and small (.154″) pin receivers; small pin models include spare hammer pin to aid in proper fit on receivers with slightly oversized holes.

Most of the pull weight is loaded on the first stage, followed by a quick, clean second-stage break. First stage, 3.2 to 5 lb.; second stage, ½ to 1½ lb. Match model allows a very low combined pull weight for superb trigger control on highly modified raceguns used in unlimited NRA High Power Rifle competition. Helps you shave those extra hundredths of an inch from your groups for a competitive edge. First stage, 1.3 to 3 lbs.; second stage, 4 oz. to 14 oz. Designated Marksman Rifle (DMR) model combines the light first stage of the Match trigger with the heavier Service second stage to reduce risk of premature release in high stress situations. Perfect for precision tactical and competitive shooting where trigger pull is not regulated. Allows a high rate of semi-auto fire; an experienced shooter can fire 30 rounds in as little as 4½ seconds. First stage, 1.3 to 3 lbs.; second stage, ½ to 1½ lbs.

Trigger Jobs

There’s a few gunsmiths that specialize in trigger jobs for black rifles. Below is a list of those that come highly recommended by fellow shooters



PWS Enhanced Mil-Spec Buffer Tube for the AR-15/AR-10 Series Rifles. Fully supports carrier from closed to open.



The PWS Enhanced Buffer Tube is the first major upgrade and improvement to the buffer tube in years!
This one piece billet buffer tube is CNC machined out of solid 7075 aluminum in order to gain lightweight strength and reliability.  This unit is specifically designed to work fit the HK416, but will also fit all mil-spec lower receivers.
The Enhanced Buffer Tube will resolve any carrier tilt symptoms exhibited by a short stroke piston AR and will reduce felt recoil.
The most notable features on this buffer tube include:
  1. One piece construction eliminating the castle nut and ensuring that when installed, the buffer tube cannot become loose.
  2. Attachment system automatically indexes the buffer tube perfectly straight.
  3. The bottom of the interior buffer tube extends a lip into the receiver, supporting the bottom rear of the bolt carrier, reducing the carrier tilt present in some piston systems.
  4. A dead blow buffer is securely installed in the rear of the buffer tube to reduce carrier speed by an average of 10%, and dramatically reduce felt recoil.
  5. Two QD sling swivel attachments are machined into the front of the buffer tube allowing ambidextrous connection of your QD slings.
  6. The buffer tube is fluted to allow debris to be pushed out of the way, and a drain hole has been placed in the bottom of the tube, allowing for draining of water when the rifle is parallel to the ground.
