The Copperhead configuration delivers maximum compactness with an overall length of approximately 14.5 in (factory specification) and a 3.5 in barrel capped by an integrated multi-lobed factory muzzle device. The aluminum receiver set wears a uniform Coyote Cerakote E190 finish for a cohesive, duty-ready look.
Its operating system is a short-stroke gas piston with a closed rotating bolt, paired with a non-reciprocating, AR-style rear charging handle. This setup is engineered for smooth cycling in a compact form factor.
The monolithic upper provides an uninterrupted Picatinny top rail and includes a right-side lightening window. This configuration ships without iron sights. Controls are ambidextrous, including the safety selector and magazine release, and capacity is 20+1 with proprietary MPX double-stack polymer magazines.
