BUILD an ARMALITE AR-10 | BUILD AR10 RIFLE

May 12, 2020 – It’s interesting to look back at this page and see how much has changed since 2014. While the information below is somewhat relevant much is out of date. I think it’s time for a new Armalite AR-10 build page.

BUILD an ARMALITE AR-10 ( Build AR 10) June 24, 2014 – We spend a lot of time on 308ar.com and it’s forum discussing various 308 AR builds from member selected parts. For some reason, the Armalite AR-10 does not seem to get the same attention. This is surprising because the Armalite AR-10 is the AR-10 It seems most folks are just buying complete AR-10’s from the factory. I decided it was time for a change, we needed to have a true AR-10 project for this site. It also seems fitting for this site to have a tribute to the creators of the one and only true AR-10, Armalite. As fate would have it and you may have noticed we recently picked up Armalite as an advertiser. With the above factors in mind, I have spent a fair amount of time going through the Armalite website product by product. I was quite surprised at the completeness of their online catalog. A shooter could easily assemble an order for an AR-10 in just a few clicks without the need to go elsewhere. The list below is that of a theoretical build to prove a point and to guide others. The rifle below would be well suited for competition, defense as well as hunting. It would be my hope to turn this project BUILD an ARMALITE AR-10 into reality soon. Albeit with a few changes to comply with local laws. Visit Armalite

Note: This page was created when Armalite was under the ownership of Mark Westrom. At that time Armalite had policies in place to assure AR-10 parts were available to rifle builders and shooters. I have noticed since Strategic Armory Corps acquired Armalite the parts availability is somewhat less.

ARMALITE AR-10 MAGAZINES

Armalite gets a little heat online for their magazine design. This stems from the now-defunct Assault Weapons ban. During that time Armalite began using modified M14 magazines to make the AR-10 AWB compliant. There were some shooters who complained of reliability issues with these modified magazines. Now here’s the thing. Those issues are long gone. In fact, Armalite redesigned the magazines and adjusted the rifles to perfection. As a service Armalite can upgrade earlier AR-10 rifles to the generation II specifications for a nominal charge. PMAGs – There is also a lot of talk about MAGPUL PMAGS in an AR-10. First off the PMAGS will not work in an ARMALITE AR-10. Secondly, while the PMAGS are a necessity for some other manufacturer’s weapons to operate reliably it’s a non-issue for the Armalite AR-10. Lastly is the cost. Armalite magazines have a reputation for being expensive. That is simply not the case. In fact, the 20 round AR-10 magazines are often a few dollars cheaper than other manufacturer’s OEM magazines. If there was an AR-10 PMAG cost would be the only reason to consider it. It doesn’t exist so the point is moot. The only example of expensive AR-10 magazines is the 25 round, capacity models. BTW is there another company that offers reliable 25 round 308 AR platform magazines? I think not. Armalite offers more magazine options than any other 308 AR manufacturer. There are options for 5, 10, 15, 20 ad 25 round capacities to satisfy any need or law. Update – It’s a different world since writing this. There are now Armalite AR-10 rifles and lower receivers that accept 308 AR PMAGS
