Platform and Drive System

The piston-driven system is the standout technical feature. Piston operation reduces fouling in the receiver compared with direct impingement designs, improving long-term reliability under extended fire or adverse conditions. For users who prioritize low-maintenance performance, the CMR’s piston system is a practical advantage for duty or range use.

Ergonomics and Controls

Ergonomic choices on the CMR emphasize ambidextrous usability: the ambidextrous charging handle and controls allow left- and right-handed shooters to operate without compromise. The adjustable MFT stock provides quick length-of-pull changes for different loadouts or protective gear. A vertical foregrip enhances low-stress control during rapid transitions and sustained strings of fire, while the included two-point QD sling attachment points support fast sling transitions and hands-free carry.

Accessories and Included Gear

Included with the firearm are two magazines (10- and 20-round), a two-point QD sling, and the factory-specified furniture. Buying a Certified Used CMR at $1,377.49 represents a value proposition for shooters seeking a high-quality platform with visible savings and quality assurance.

The CMR is well-suited for roles that demand reliable semi-auto performance with conservative recoil impulse and modular ergonomics. For detailed specs, photos, and to complete a purchase, View product details and pricing.
