The Bravo Company Manufacturing Gunfighter (brand part no. LRG-STK-MOD-0-SPMD-BLK) is a complete AR-15 lower receiver group chambered in .223 Remington/5.56 NATO, built to mil-spec to ensure compatibility with a wide range of parts and accessories. It comes fully assembled and ready to attach to any mil-spec complete upper, forged from 7075-T6 aluminum and hardcoat anodized black, with a BCM Gunfighter grip, Mod-0 SOPMOD stock, enlarged polymer trigger guard, and BCM’s MK-2 buffer system already installed. The MK-2 buffer system splits the difference between rifle- and carbine-length systems, giving the length of pull of a rifle stock with the adjustability of a carbine stock, and it’s specifically noted for improving reliability and cutting felt recoil on short-barrel builds. BCM built its reputation supplying duty-grade rifles and components to military and law enforcement users, and this lower group carries that same mil-spec discipline into a ready-to-build package.
