The TacFire Pistol Upper Assembly (brand part no. BU45ACP7) is a complete, ready-to-install AR-platform upper chambered in .45 ACP with a 7-inch Black Nitride barrel. TacFire builds the receiver from black anodized 7075-T6 aluminum and pairs it with an M-LOK handguard for mounting lights, grips, and other accessories.
