Brownells BRN-180 side--charging upper receivers were designed to work with any standard, mil-spec AR-15 lower. Now Brownells is releasing its own lower receivers designed to work specifically with its BRN-180 uppers.

The new lowers, made from billet 7075 T-6 aluminum with a hard-anodized finish, do away with the traditional receiver extension threads, and in their place have a milled-in Picatinny rail section for mounting stocks or braces. They also feature an oversize trigger guard and a threaded bolt catch pin and a captive set screw for the takedown pin detent spring.

The lowers will be available in two varieties. SRP: $149. Booth #13018. (brownells.com)
