CMMG Dissent AR-15 Pistol

AR-15 pistols are fantastic for portability, maneuverability, and use in tighter spaces like trucks. Of course, if your AR-15 pistol is chambered in a handgun caliber, it’s not going to be quite as effective as rifle caliber models. The CMMG Dissent gives gun owners the best of both worlds, and then some, with its super-compact, bufferless profile, rifle caliber chambering options, and overall quality.

CMMG provides the following details about their Dissent AR-15 pistol:

Outfitted with CMMG ZEROED parts and accessories and donning AR15 modularity, the CMMG DISSENT boasts superior firepower in a small familiar package and will initially be offered in three different calibers with .300BLK and 5.56x45mm utilizing a Direct Impingement operating system, while the 5.7x28mm version utilizes CMMG’s patented Radial Delayed Blowback operating system. Both .300BLK and 5.56x45mm will accept and ship with their respective 30-round Magpul PMAGS and the 5.7x28mm will accept and ship with the 32-round CMMG 5.7x28mm Gen II Conversion Magazine.

The CMMG Dissent features the manufacturer’s patent-pending Compact Action, which is how it’s possible to run the gun without the receiver extension and buffer assembly installed. This technology utilizes dual guide rods and springs that are contained in the upper receiver to cycle the gun’s action. It’s compatible with Direct Impingement and CMMG’s patented Radial Delayed Blowback operating systems. This is a fascinating design and promises to broaden the company’s lines overall.
