The CNC Firearms HK MR556 Night Ops is a refined AR-style rifle that blends HK’s proven MR556 architecture with CNC Firearms’ distinctive Night Ops Multicam finish. Built around a short-stroke gas piston system and a 11.00" barrel, it is engineered for smooth cycling, reduced fouling, and dependable performance over extended shooting sessions.

This configuration is well suited for range use, training, and general-purpose defensive roles where reliability and controllability matter. The Multicam pattern provides a subdued, modern aesthetic, while the 30-round capacity supports longer strings of fire between reloads. Together with HK’s reputation for precision engineering and CNC Firearms’ attention to detail, this MR556 variant offers a balanced blend of craftsmanship, durability, and practical performance.
