Compact, maneuverable firearms that retain full-function performance are highly valued for personal defense and tactical range work. When space, concealment, and rapid handling matter, modern AR-style pistols engineered for reliability and portability address those needs without sacrificing modularity or sighting options.

CMMG DISSENT is a purpose-built buffer-less AR15 pistol line that leverages the company’s patent-pending Compact Action to deliver a truly stowable Personal Defense Weapon. Each model features a 6.5-inch free-floated barrel and a 5.5-inch M-LOK handguard, making this among the shortest platforms CMMG has produced. Priced at $1777.99 and listed under the Semi Auto category, the DISSENT prioritizes a compact footprint while preserving the familiar AR ergonomics. Shop this product

Design & Compact Action

The patent-pending Compact Action eliminates the traditional buffer tube assembly, shortening overall length and allowing for more practical storage in small cases or vehicle compartments. From a tactical standpoint, removing the buffer tube opens options for more compact braces and chassis setups while maintaining reliable cycling in a Semi Auto configuration. CMMG’s engineering focus is apparent in the integration of the action with a short, free-floated barrel to keep barrel harmonics consistent despite the compact package.

Barrel, Handguard, and Handling

The 6.5-inch free-floated barrel provides a balance between velocity and compactness; it gives shooters a controllable sight radius for close-quarters work and enough barrel length to stabilize common defensive projectiles. The 5.5-inch M-LOK handguard offers modularity for lights, short foregrips, and sling mounts without adding unnecessary bulk—ideal for operators who must configure a PDW-style build.
