TacFire Rifle Upper Assembly, .45 ACP with 16-inch Barrel

The TacFire rifle upper assembly (brand part no. BU45ACP16) is a completely built .45 ACP upper ready to drop onto a compatible AR-platform lower. It pairs a 16-inch black nitride-finished barrel with a black anodized 7075-T6 aluminum receiver and an M-LOK handguard, and it ships with a bolt carrier group included, so there is no need to source parts separately. The upper is optic ready with no iron sights included, leaving the top rail open for the red dot or scope of the builder’s choice. This assembly gives AR owners a straightforward way to add a .45 ACP pistol-caliber option to an existing lower without buying a second complete rifle.
