Official Armalite AR-10 Lower Receivers | AR-10A | AR-10B

These are the Official Armalite AR-10 Lower Receivers. AR-10 is the registered trademark owned by Armalite to prove it. No other firearm is an AR-10 no other manufacturers weapon should be referred to as  an AR-10. Armalite is the only AR-10® period. Referring to any other brand 308 AR as an AR-10 only adds to the confusion of the platforms


Armalite AR-10 Lower Receivers!

Armalite AR-10 Series “A” Lower Receivers can utilize Magpul LR 308 PMAG Magazines as well as other DPMS LR-308 compatible magazines!

Armalite AR-10 Series “B” Lower Receivers utilize Armalite proprietary magazines originally derived from M14 magazines!

As if the 308 AR versus AR-10® platform debate isn’t confusing enough Armalite brings confusion to their own platform. Armalite AR-10 lowers are available in two styles. The original AR-10 A series and the AR-10 B series.

Why does Armalite offer two different AR-10 lowers? Original Armalite “waffle”  magazines are actually the basis of DPMS LR-308 and KAC SR-25 magazines. During the 1994 Bill Clinton Assault Weapon Armalite decided to switch designs to the modified M14 magazines to ensure customers would have an ample supply of 308 magazines.


Armalite AR-10 Lowers

but when you Armalite AR-10 lowers will not win any beauty contests but when you buy authentic AR 10 lowers you are buying battle tested hardware that has withstood the test of time. That’s more than most other 308 AR manufacturers can say. The Armalite AR-10 is the real deal.

A gun owner does not need to be a genius to understand what is at risk with the upcoming presidential election. Hillary Clinton’s gun control position is well known. If elected she no doubt has the perfect timing and opportunity to devastate or Second Amendment and god given right. She no doubt will appoint a Superior Court Justice that will severely tip the vote more anti-gun liberal than it is now. Donald Trump is something altogether something different and an unknown. We do know despite coming out very pro gun he is also a New York Republican. That should not be underestimated. Learn from past mistakes and  buy 308 AR Lower Receivers Now.

I have lived in a state that had an assault weapons ban before the federal assault weapons ban of 1994. This state implemented further restrictions after the Sandy Hook shootings.

Why should I buy 308 AR Lower Receivers?

Why should I buy 308 AR Lower Receivers? There are a few answers to this question.

  • 308 AR Lower Availability – 308  Lowers stop being sold as separate parts as supplies dwindle. This is because firearms manufacturers need to commit inventory to complete rifles. This is simple economics
  • 308 AR Lower Cost –  The 308 AR Lower Receiver is the “Registered” part of the gun. Individual 308 Lowers are much cheaper to purchase than a complete 308 AR Rifle. In fact you can probably buy a lifetime supply of 308 Lowers for the cost of one complete 308 AR Rifle.
  • Grandfathered Firearms –   This detail is very important. Historically when gun laws change what a shooter currently owns with be “grandfathered” Meaning what you currently own you can do what you wish with to some degree. Gun law changes typically begin with new purchases with limited or minor changes to existing guns. Bottom line it’s better to own “Something” rather than “Nothing”

What 308 AR Lower Receivers Should I Buy?

While the choice of which 308 AR Lower Receivers to buy is personal preference I will attempt make a few points to consider before buy. In my opinion it’s best to buy 308 lowers that are as DPMS 308 compatible as possible (Not DPMS G2). Avoid the designs that use unique Bolt Carriers, Safety Selectors and Barrel Extensions. The DPMS 308 AR Upper and 308 AR lower are the most copied receiver profiles. This fact makes the style pretty interchangeable. If you are considering a 308 AR Lower that is somewhat unique in profile it would also be a great idea to buy the matching upper receiver at the same time.

 

Below are links to 308 AR Receivers mostly at Brownells. Keep a watchful eye on the Aero Precision Website. They are expecting to be caught up with the 308 rifle backlog very soon. Don’t forget to visit your local gun shop. Often they have overpriced but available stock. Look for gun shops that specialize in AR Rifles and Silencers.

Extended Magazine Catch Button APRH308185

Note: Aero Precision 308AR M5 Lower Receivers require their own Extended Magazine Catch Button APRH308185. It’s $5 Personally I think it should be included with their lower receivers.

The Extended Magazine Catch Button is a drop in replacement for the standard lower receiver magazine catch button. This extended button is longer, allowing it to protrude the proper distance when used with our M5 Lower Receiver.
