Rise Armament BCG .223/5.56 Black – AR-15 Bolt Carrier Group

The Rise Armament BCG .223/5.56 Black is a drop-in replacement bolt carrier group engineered for reliable AR-15 platform operation. This BCG delivers consistent cycling in .223 Remington and 5.56 NATO chambered rifles, whether you're building a new upper or replacing a worn factory carrier group. The black nitride finish reduces friction and resists corrosion better than standard phosphate coatings.

Machined from 8620 steel with a 9310 steel bolt, this carrier group features proper staking, a chrome-lined interior, and full MPI/HPT testing. The black nitride finish is applied inside and out for enhanced wear resistance and easier cleanup. Installation is straightforward—this is a drop-in component that requires no fitting or gunsmithing.
