CMMG Dissent MK4 Features

The CMMG Dissent MK4 operates on a Compact Action-Direct Impingement system, ensuring smooth and reliable performance. The 16.1″ barrel, crafted from 4140CM steel with a Salt Bath Nitride (SBN) finish, provides exceptional durability and accuracy. The barrel’s 1:7 twist rate is optimized for the .22 ARC caliber, ensuring superior ballistic performance. The CMMG ZEROED Muzzle Brake reduces recoil and muzzle rise, allowing for faster follow-up shots.

This rifle features a Dissent side charger that is reversible, offering versatile handling options. The adjustable gas block allows for fine-tuning of the gas system, optimizing performance for various ammunition types. The DISSENT 7075 T6 aluminum upper and Mk4 forged 7075 T6 aluminum lower receivers ensure a lightweight yet robust construction. The rifle also includes a proprietary 15″ CMMG handguard, providing ample space for accessories. The side-folding stock and the DISSENT folding stock adapter enhance portability and ease of storage.
