Black Powder AR-15

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

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.
