Modern shooters looking for a durable, low-recoil centerfire platform for training, varminting, or precision plinking need a rifle that balances reliability, adjustability, and ballistic performance. The right semi-auto that handles modern .22 ARC ammunition can deliver centerfire energy with controllable recoil and excellent barrel life when built from quality materials.
CMMG DISSENT MK4 operates on a Compact Action-Direct Impingement system, delivering smooth, reliable cycling and a familiar AR-style manual of arms with reduced felt recoil. The reversible Dissent side charger provides ambidextrous handling options that suit duty, training, or personal defense setups. Shop this product

Performance and gas system
The Mk4’s Compact Action-Direct Impingement operation paired with an adjustable gas block lets you tune the system for a wide range of .22 ARC loads. Fine-tuning gas flow reduces wear and improves reliability across supersonic and subsonic factory offerings. The included CMMG ZEROED Muzzle Brake mitigates recoil and muzzle rise, speeding follow-up shots and keeping the sight picture stable.
Barrel construction and ballistics
Materials and twist rate
A 16.1″ barrel forged from 4140CM steel with a Salt Bath Nitride (SBN) finish gives corrosion resistance and a hard-wearing surface that stands up to sustained use. The 1:7 twist is optimized for the .22 ARC caliber, stabilizing heavier, high-BC projectiles for flatter trajectories and extended effective range compared with traditional rimfire options. For varmint work, tactical drills, or economical training with centerfire performance, that twist rate and finish are meaningful advantages.
Controls, build, and ergonomics
The DISSENT 7075 T6 aluminum upper and Mk4 forged 7075 T6 aluminum lower keep weight in check while providing a rigid platform for optics and accessories. The reversible side charger, combined with an adjustable gas block and proven bolt/carrier design, makes this an adaptable rifle for right- or left-handed shooters and varied mission profiles.
