Parker Mountain Machine is proud to bring a Battery control device to the market for the AR15/M4 weapon system (will also work on MR556 and Sig 516 rifles).
NOT COMPATIBLE WITH NON-MILSPEC UPPERS LIKE BILLET UPPERS OR THE NEW BCM MK2 UPPERS.
Much like the Battery Devices found on our other weapon systems PMM’s B.C.D. 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.
Additionally the B.C.D’s main paddle is larger with finer serrations for extra grip while engaging the bolt release of the AR15 rifle traditionally.
Machined in-house out of 6061 aluminum then hardcoated per military standards. The PMM B.C.D. is a low cost and effective way of improving the operating functions of your rifle.
