Purchased rhe AR 15 lower assembly and it took a awhile to receive but a very high quality lower. Very light, great color match to upper, and functional in all aspects, and magazines release and install easily. I will purchase from again, but do expect a waiting time to receive.

Excellent product.

I mated this lower to a Bear Creek Arsenal 7.62x39 upper. Very comfortable, shoots great. The lighter weight makes it much easier on handling. Thank you folks so much for such a fine product.

AR 15 polymer lower receiver TENNESSEE Arms
Posted by Edward on 6th May 2021

It took about 230 rounds to loosen up. The hammer would get stuck and I'd have to keep resetting the safety fire a shit and repeat about 15 times until it loosened up to run full semi-auto. Need more range time but great so far.

Blog Post About Product

Washington and Illinois AR15 Bans

Washington and Illinois have both recently passed laws banning the sale and distribution of assault-style weapons, high capacity-magazines, and switches that convert handguns into assault-style firearms. Both laws were met with strong opposition from gun rights groups, and in response, both states have faced lawsuits.
