The CNC Firearms HK MR556 "Night Ops" Custom Package is a fully realized, turn-key, low-light firearm system built on Heckler & Koch's legendary short-stroke gas piston platform. Chambered in 5.56 NATO with a compact 11.0" barrel, this custom-finished Multicam Black AR pistol is engineered to operate seamlessly across all conditions, delivering relentless precision, flat recoil control, and superior suppressed performance straight out of the box.

At the core of the optic setup is the world-class Vortex Razor HD Gen III LPVO, mounted rock-solid in precision-machined Geissele 34mm Scope Rings for crisp glass clarity and rapid target acquisition from close quarters out to extended ranges. Muzzle signature and sound suppression are handled by the high-performance Otter Creek Labs (OCL) Polonium K 5.56 Suppressor, mounted via a heavy-duty Method Dynamics Muzzle Device and Method Dynamics Hub Assembly. For low-light operational superiority, the setup is outfitted with a high-output Modlite Weapon Light secured on an ultra-low-profile Arisaka Inline Scout Mount, wired directly to a Noxon Fuze Remote Switch for ergonomic, ambidextrous light activation. Driven by HK's famous piston reliability and clad in a custom Multicam Black finish, this complete system stands as the apex of modern tactical capability.
