CMMG Dissent Mk3 Features The CMMG Dissent Mk3 is chambered in 8.6 Blackout the larger sibling to .300 Blackout that brings the same short-barrel philosophy to the AR10-sized platform using heavier .338 caliber projectiles. A quick 1:3 twist rate stabilizes those heavier bullets even out of the 12.5 inch barrel letting the cartridge perform well both suppressed and unsuppressed. The chrome moly barrel wears a black nitride finish and is threaded 5/8x24 to accept the included CMMG Zeroed muzzle brake giving shooters a ready mounting point for a suppressor as well. A direct impingement operating system cycles the action reliably across a range of loads and suppressor configurations. CMMG s Zeroed control package equips the Dissent Mk3 with an ambi charging handle single-stage drop-in trigger and 60/90 degree ambi safety selector all tuned to work together rather than sold as separate aftermarket parts. The Coyote Tan Cerakote receiver carries a full Picatinny top rail for optics mounting backed by an M-LOK handguard for lights grips and other accessories. Feeding comes from Magpul PMAGs for reliable 20 round capacity and the pistol measures 23 inches overall at 7.3 lbs. For shooters wanting the reach and power of 8.6 Blackout in a compact AR pistol the CMMG Dissent Mk3 is available for sale at GrabAGun.
