Brownells and KAK Industry have partnered to build the best performing complete upper at an unbeatable price. This premium complete upper features a chrome-lined barrel, chrome-lined phosphate K-SPEC Enhanced BCG, Brownells-exclusive PentaComp muzzle device, and a rock-steady free-float KAK Industry MLOK handguard. 100% American made for years of dependable service.
The K-SPEC Down Vent BCG represents unrivaled reliability, featuring Slotted Angled Carrier Rails, Dual Ejectors, and downward gas vents that redirect gas underneath the carrier instead of out at the shooter’s face.
