For operators and serious enthusiasts who prioritize reliability and controllability in a tactical semi-auto, platform selection is about real-world performance, not marketing. A robust piston system, ambidextrous controls, and components that resist wear under sustained use make the difference when precision and stability matter most.

Key features and tactical benefits

The piston operation reduces carrier tilt and limits heat transfer into the action compared with direct impingement systems, improving long-term reliability in high-round-count sessions. The coated bolt assembly with roller bearing minimizes friction and helps maintain consistent cyclic timing—important for accuracy and parts longevity.

Controls and ergonomics

Ambidextrous safety and an ambidextrous bolt release let left- and right-handed shooters manipulate the rifle without changing grip or stance. The Mission First Tactical buttstock offers a secure cheek weld and repeatable shoulder placement for faster follow-up shots and better shot-to-shot consistency.

Durability and match-ready fit

Anti-walk pins are a practical upgrade for any hard-use rifle, preventing roll-out under recoil and transport. The included muzzle brake reduces perceived recoil and muzzle rise, enabling quicker target reacquisition during rapid strings of fire.

As a Certified Used firearm, this CMR comes with a ‘no questions asked’ return policy, giving buyers confidence that the rifle meets a high standard of condition and function. For full specifications and to confirm current inventory at our retailer, View product details and pricing.
