.308 Lower Receiver Compatibility:

Upper Assembly: Any DPMS Generation 1 upper (e.g., CMMG, Aero Precision, Fulton Armory, and DPMS). We have found that the CMMG MK3 uppers fit best with our lowers.

Lower Parts Kit: Due to the varying quality and compatibility of .308 builds, we recommend using CMMG's MK3 .308 LPKs, especially their bolt catch. 

Magazine: The SR25 or LR308 mags will fit. Magpul's .308, 10 and 20 round mags work best.

No FFL is required to purchase this lower receiver. This billet 6061 aluminum 80% lower receiver is not considered a firearm and is compliant with the gun control act of 1968 not classified as a firearm as defined in 18 U.S.C. 921(a)(3).

Quality product

"The 80% Arms AR 10 lower receiver is excellent quality, perfectly formed, and easy to finish. When complete, all parts fit as designed. Anyone with average skill with hand tools and a router can build one."


Just like it says...EASY!

"I received this item during a busy week, but that weekend I put it to work. I finished a billet AR-10 lower in a longer amount of time than most...I didn't really watch the clock, but I did take my time as this was my first 80% lower of any kind. The next one will go much quicker. My lower came out very clean...happy to say that it was cleaner than most that I have seen in pictures. You can not see any of the drill marks in the bottom of the pockets. All the surfaces crisp and clean and none of the finish was damaged on the rest of the lower. I haven't ordered my parts yet, but am doing some research and getting ready to click that ""checkout"" button. I will write back if I find any trouble with anything....I don't suspect that I will. Tips: Take your time. Be willing to come back and do more later. Google and watch the videos of others and incorporate what you think sounds like good ideas. I have a lab for building prosthetic limbs, so I had access to a power tool room that is designed for doing some dirty work, air hoses, good lighting, drill press, nice router, good lighting, dust collection and a shop vac, good lighting. Oh, did I mention good lighting makes things go much smoother. Have fun!!"
