The CMMG Dissent Br3 .308 Win rifle is the non-threaded version of CMMG’s Modern Utility Rifle, with a 16.1-inch Empire profile barrel, a recessed crown and an Armor Black Cerakote finish (brand part no. 38A260C-AB). It blends traditional bolt-gun controls with the versatility of a 30-caliber carbine, using a Magpul SGA stock that is compatible with Remington 870 stocks. CMMG designed the Br3 as the go-to platform for heavily restricted states. A reversible crossbolt safety, a reversible side charger and an adjustable gas block round out the controls. It ships with two 10-round Magpul PMAGs.
