CMMG Dissent BR3 Features The CMMG Dissent BR3 is built around a direct impingement operating system feeding from a 16.1 inch barrel with a 1:10 twist machined from chrome moly steel and finished in black nitride for lasting corrosion resistance. A reversible non-reciprocating forward side charger lets the shooter rack the bolt from either side without the handle moving back and forth keeping it clear of mounted optics and accessories. M-LOK slots along the handguard allow for lightweight accessory attachment without adding unnecessary bulk to the rifle s overall profile. A 5/8x24 threaded muzzle accepts the CMMG ZEROED muzzle brake included with the rifle helping tame recoil from the .308 Win chambering. The Br3 billet 7075-T6 aluminum lower pairs with a DISSENT Mk3 upper receiver featuring a full length Picatinny rail and that lower is compatible with the entire line of DISSENT Mk3 uppers giving owners room to expand their build later. Ambidextrous magazine releases and a reversible crossbolt safety give left and right-handed shooters equal access to the rifle s controls. A Magpul SGA stock adapted from the Remington 870 shotgun stock line pairs with a single stage ZEROED trigger tuned specifically for the Br3 platform. Finished in Coyote Tan Cerakote over the receiver with a black nitride barrel the rifle ships with two 10 round Magpul PMAGs giving shooters a complete compliant large frame rifle ready to run for sale at GrabAGun.
