The TacFire .308 Win 12-inch Pistol Upper with BCG (brand part no. BU30812) is a complete upper chambered in .308 Winchester with a 12-inch barrel, built for a large-frame AR pistol. It ships with a bolt carrier group already installed, so it mates directly to a compatible large-frame pistol lower without sourcing extra small parts. The 12-inch barrel strikes a balance between maneuverability and the ballistic advantage of .308 over a shorter-barreled build. It is a solid option for builders assembling a large-frame AR pistol.
