2A Armament AR-15 Bolt Carrier Group
This bolt carrier group (BCG) is manufactured by 2A Armament. It is made for 5.56/.223 AR-15 style rifles and is a full mass, non-adjustable BCG made out of QPQ Nitride material. What sets this bolt carrier group apart is a more balanced distribution of weight. The majority of the carrier mass is located at the tail of the carrier, giving it a more balanced weight when added to your AR-15.
2A goes even further with weigh distribution by the overall design during the firing cycle. This carrier group glides along the plane, giving a more even distribution of weight, into the shooters shoulder instead of the shooters primary support hand.
