PMM’s BCD allows the shooter full control of the AR15 bolt carrier with minor movement of the trigger finger saving the shooter precious time during magazine changes and battery manipulation.
The B.C.D’s main paddle is larger with finer serrations for extra grip while engaging the bolt release of the AR15 / M4 rifle traditionally.
