The Bravo Company Mfg (BCM) complete pistol lower receiver group (part no. LRG-PISTOL) drops a fully assembled AR-15 pistol lower into your build, chambered for .223 Remington/5.56 NATO on a multi-caliber receiver. Unlike a bare stripped lower, this group arrives with the BCM PNT trigger, BCM Pistol Grip Mod 3, trigger guard, QD end plate, and a pistol-length receiver extension already installed, saving you the assembly work of sourcing and fitting each internal part yourself. It is built for shooters assembling a pistol-format AR build meant to run with a stabilizing brace rather than a shoulder stock.
