The modern AR-10 platform has evolved into a highly capable tool for shooters who demand precision, durability, and controllable recoil. This review walks through the features that make the CMMG Mk3 a standout Semi Auto option for range work, competition, and defensive applications.
CMMG Mk3 
Design and Construction
The CMMG Mk3 pairs an aluminum lower with a stainless steel Heavy Taper Barrel to balance weight savings and thermal stability. The heavier taper profile increases rigidity for improved accuracy under sustained strings of fire while resisting barrel whip common to lighter profiles. A Magpul Stock provides proven ergonomics and modular adjustment for cheek weld and length of pull.

Barrel and Muzzle System
The stainless steel Heavy Taper Barrel is a central performance feature—its increased mass forward of the receiver improves harmonics and helps maintain point-of-impact during extended shooting. The rifle ships with a ZEROED SV Brake, engineered to reduce felt recoil and muzzle rise without adding unnecessary flash or blast to the shooter’s position.
