The 2A Armament Full Mass Carrier (FMC) was designed as a high-quality, full mass bolt carrier group, with an emphasis on enhanced weight distribution. By relocating the bulk of carrier mass to the tail, the FMC keeps the firearm in a more balanced state. Weight that would normally be over the magazine well is now over the pistol grip on an AR-15 rifle when at rest. The distribution of weight is further utilized during the firing cycle as the FMC reciprocates along the plane located within the pocket of the shooters shoulder and primary support hand, instead of out in front between the magazine well, and primary support hand. The FMC can give the shooter an extremely reliable full mass bolt carrier group, with a weight distribution advantage over standard carriers on the market.
NOTE: Does not support the use of forward assist. Not compatible with full auto systems
