Missouri-based CMMG this week announced a new series of Compact Action AR-15 pistols in three calibers. 

The new CMMG Dissent is billed as the company's "most stowable PDW" and blends AR modularity – the upper pairs with any mil-spec AR-15 lower – with a bufferless action that creates a platform just 14.7 inches in overall length. Available in 5.56 NATO, 5.7 NATO, and .300 Blackout, weight in all versions is just 4.6 pounds. Standard features include a TriggerTech AR-D 2-stage trigger, a forward non-reciprocating side charging handle, and a 6.5-inch barrel inside a 5-inch M-LOK handguard. A full-length 1913 Picatinny top rail is there for sights and optics while a short rear-mounted Pic rail is there for stocks (NFA rules apply) and braces (for now). 

Receivers are made of 7075 aluminum and the guns run what CMMG calls their Compact Action Radial delayed blowback system, which uses a set of dual guide rods and springs contained within the upper receiver to cycle the action. 

More on that action:

The new CMMG Dissent is available in three calibers: 5.56 NATO, 5.7 NATO, and .300 Blackout. Both .300 BLK and 5.56 will accept and ship with their respective 30-round Magpul PMAGs, and the 5.7 will accept and ship with its 32-round CMMG 5.7 Gen II Conversion Magazine.

Each caliber is also available in six colors. 

MSRP on the new CMMG Dissent line, which is not shipping quite yet, is $1,995, each including two magazines. 

The company made sure to get some preproduction models out in the hands of gun tubers and several reviews have dropped in the past couple days, so if you are curious, check out the below from Gavintoobe, Honest Outlaw, IV8888, 704 Tactical, and Pew-Pew Tactical's Johnny B.
