The CMMG Dissent MK4 is a compact, semi-automatic AR-style pistol chambered in .300 AAC Blackout with a 10.50-inch threaded barrel. Its design eliminates the conventional AR-15 buffer system to deliver a shorter, more portable profile while retaining modular AR functionality. An adjustable gas block lets shooters tune the gas system to suit subsonic or supersonic 300 BLK loadings, and a 1913 Picatinny rail end plate accepts a folding pistol brace or stock.
