The CMMG .300 AAC Blackout AR pistol redefines what a compact AR platform can do. Built on CMMG's patent-pending Compact Action, this 6.5" barreled pistol eliminates the traditional buffer tube entirely—the whole recoil system lives in the upper receiver, giving you genuine portability without sacrificing the controls and ergonomics you expect from an AR. At 14.7" overall and just 4.8 lbs, it's a serious .30-caliber option for close-range work, home defense, or specialized tactical needs.
What sets this DISSENT apart is modularity with intention. The side charger can be repositioned for left or right-handed shooters, and the rear receiver sports a 1913 Picatinny rail so you can dial in whatever brace or stock fits your mission. The SLR adjustable gas block lets you tune the system for both supersonic and subsonic .300 Blackout loads—critical when you're running suppressors or switching ammunition types. The included TriggerTech AR-D trigger was co-developed with CMMG and delivers a crisp 4 lb pull optimized specifically for this platform.
Details matter in a specialized platform. The 6.5" barrel wears a 1:7 twist and 4140CM steel, paired with a CMMG ZEROED linear compensator (5/8 x 24 threads). The lower is Mk4 forged aluminum, upper is DISSENT spec aluminum. You get a Magpul 30-round .300 BLK PMAG and all the CMMG ZEROED components—grip, trigger guard, safety selector with 60/90 degree options. Finish is Cerakote, built to handle field use.

Each pistol ships with a Magpul 30-round .300 BLK PMAG.
The SLR adjustable gas block allows you to tune the system for the specific ammunition you're running.
