The Black Rain Ordnance Spec15 Bolt Carrier Group (brand part no. BRO-SPEC15-BCG) is a complete 5.56 NATO carrier group finished in black nitride for shooters who want a durable, low-maintenance drop-in for their AR-15 or M4-pattern upper. Black Rain Ordnance builds the Spec15 to run in mil-spec uppers without modification, so it is a straightforward way to replace a worn carrier or complete a fresh build. The nitride coating adds corrosion and wear resistance beyond a standard phosphate finish while keeping the bolt running smooth between cleanings.
