TacFire .308 Win Rifle Upper Assembly, 18 inch with BCG

The TacFire .308 Win rifle upper assembly (brand part no. BU30818) is chambered in .308 Winchester and completely built around an 18-inch black nitride barrel, a more maneuverable option than TacFire’s 20-inch upper while still delivering solid .308 velocity. The 7075-T6 aluminum receiver is black anodized and paired with an M-LOK handguard, and the assembly ships complete with a bolt carrier group, so it’s ready to mount straight onto a compatible AR-10 pattern lower. It’s built optic-ready with no fixed sights, giving builders a clean slate for their glass of choice.
