Product Details

​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).


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.

CNC’d 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.

Product Features:

  • Finished in a 8625 type 3 class 2 industry standard hardcoat. In colors FDE or black
  • Mounting hardware and loctite included
  • Limited Lifetime Warranty.
  • Installation is simple and is done in minutes.
  • No permanent modifications to the rifle.
  • Light weight less than 1 oz with Hardware.
  • Does not contact any critical components of the AR15 during articulation.

  1. Andrew H.

    Well made and I have one on my AR as well as my SCAR. Improves on the ergonomics of both platforms

  2. Adam B.

    Quality is top notch. PMM never disappoints, there machine work is excellent. Adding a Battery assist device (which takes 15 seconds) on your rifle will surely shave seconds offbof anyone’s reload time, and this one looks nice too. Imo, better than the Magpul BAD Lever, and it has a bigger bolt release paddle which is very easy to get to. Definitely worth the money

  3. Dustin V.

    The best Battery control lever on the market. It doesn’t dance around like a bad lever. It securely clamps to the bolt catch/release and has a huge surface area if you wanna smack it southpaw.

    Received it a few weeks ago and finally installed it tonight (06-23-19). I haven’t used it in live fire (obviously) but I did a couple of functions checks and it seems to work properly. Installation was a breeze, just make sure you have a Torx T10 tool available. I gave it the 5 stars because of its simplicity I can’t imagine anything going wrong with it, famous last words.

    I purchased the PMM B.C.D. after previously owning the magpul version. I found the PMM to be very well machined. It is lightweight and durable. I find the method in which the PMM attaches to the bolt catch to be much sturdier than other variants, and much more secure. Overall very impressed by this device and have recommended to others.
