Black Powder AR-15

CMMG have announced an .50 Black Powder AR-15 Upper!

Picture 20-1

To fire, the powder charge and bullet are loaded via a ramrod. Using a standard magazine with a single shot follower, an unloaded 5.56 case is loaded into the mag, inserted in magazine well and loaded just like a standard rifle.

Once the rifle is fired, the empty brass is ejected manually and then reloaded.

It is a modified .223 case that uses a 209 primer. Currently .50 cal. Should have pricing and other specs tomorrow.

Interesting! As one commenter said

Can you imagine the face of an unsuspecting
game warden the first time he runs across these..

They have yet to announce pricing.

This isn’t a loaded case, it is a 209 primer in a piece of .223 brass. There is no way a live round or a blank will load into the “chamber”.


A video of it in action. Actually, it looks pretty good.

    As if the AR didn’t have enough trouble with fouling 😉

  • HAHA, good one!

  • M. Werner

    Having considerable experience cleaning black powder weapons, I agree with Thomas…All those little nooks and crannies in the AR….Yechh.

  • Captain Demo

    This Rocks… I would love to pull this out of the case in front of “the boys” and say something like “enough of this kidding around, I am going to go get me some meat!”

  • Dino

    Why not?

    And why a single-shot follower in the mag? If the primer-carrying case could be made to feed with multiple rounds, then at the range or in the event of a misfire, one could work the handle and foop, fresh primer.

    In California, there is no government vetting process to purchase black powder firearms.

    Does this mean that this gun can be bought without filling out any state and/or federal forms or going through any background checks?

  • Aaron

    I don’t know about California, but here in Michigan we have a similar law. The exception is that if the black powder firearm can be converted to fire cartridges, it must be processed as a regular firearm. Many states do this.
