Platform Highlights

As a Semi Auto offering from Cmmg, this rifle’s components are selected to cover both defensive and precision roles. The Geissele trigger improves shot-to-shot consistency and follow-up speed. The Key‑Mod handguard reduces weight and allows modular attachment of lights, offset sights, or bipods. Dual muzzle brakes give the operator options for recoil and flash management depending on duty or range use.

Optics, Mounting, and Practical Use

The included Bushnell 10X40 Elite Tactical scope on a Burris P.E.P.R. mount positions this rifle for medium‑to‑long range target work right out of the box. The scope and mount pairing are reliable for repeatable zeroing and rapid return-to-zero after transport.
