North Carolina-based Bear Creek Arsenal has just announced they are branching out from their traditional 5.56 AR fare to blowback-actioned pistol caliber carbines.
Using AR styling and Glock-compatible mag wells, the AR-10MM and companion AR-45 platforms are suppressor ready with threaded muzzles. Both use side-charging handles and an 8-ounce buffer.
Each will be available in 10.5-inch and 16-inch versions while the .45 will also be offered in a 7.5-inch large format pistol.
