    2-Pack AR15 80% Receiver w Drilling Jig & Tools

    Best lower on the market. The brass strengtheners used at the pertinent points only add to the high quality. The tools are easy to use & long lasting. I'll definitely buy again.

    I've never been dissapointed in anything from Tennessee Arms. These 80% lowers do not disappoint! With the included jig they came out relatively clean and run great with my .223 upper installed!

    AR15 80%

    Posted by J Hoogestraat on 17th Nov 2021

    They are sitting in a drawer. I did not machine them nor do I hope I ever have to. But I'm sure they work fine. The holes and threading looked great. With the metal insert I am sure it will last just as long as aluminum.

    AR15 lower

    Posted by Eric Price on 4th Nov 2021

    Jig is very loose, I’ve purchased 2 others about a year ago and the jigs were way sturdier. The new half length jig doesn’t support the lower nearly as well.
