Product Description

Considered by some to be the American answer to 7.62x39, the 300 Blackout has been modified to use the same magazines and bolt as the common 5.56 NATO. The 300 Blackout allows for shooting of various grain weights and performs exceptionally with subsonic ammo and suppressors. The BCA .300 Blackout Billet Upper Receiver is made from 7075 aircraft-grade aluminum billets with a parkerized finish and is compatible with any mil-spec AR-15 lower. The rifle length upper has a 16” heavy barrel and features a 1:8 twist rate, with a pistol length gas system. It includes a 15 1/4” MLOK rail, an M4 flat-top billet upper receiver, a BCA bolt carrier group, a flash hider, and a rear charging handle.
