CENTURION ARMS MK12 Mod 0 5.56mm NATO 18in 30rd Semi-Automatic Rifle (MK12-MOD0-RFL)

The CENTURION ARMS MK12 Mod 0 Rifle was built to reach out and deliver - with the kind of first-round precision that only a purpose-engineered designated marksman platform can provide. Rooted in the combat-proven legacy of the United States Navy Mark 12 Special Purpose Rifle, this faithful reproduction captures every defining characteristic of the original Mod 0 configuration: the 18" match-grade stainless barrel, the free-floating PRI Gen III handguard, the OPS Inc. brake and collar, and the Centurion Arms Advanced Sniper Trigger - all wrapped in forged mil-spec receivers built to the same standards that armed Naval Special Warfare operators downrange.

The MK12 SPR concept was born from a simple but powerful idea: give a special operator the extended reach and precision of a designated marksman rifle without abandoning the familiar controls and ergonomics of the AR platform. Developed by the Naval Surface Warfare Center, Crane Division, the MK12 filled the critical gap between a standard M4 carbine and a dedicated sniper system - and it did so with remarkable effectiveness. The 18" free-floating barrel, tuned for the 77-grain Mk 262 OTM cartridge, unlocked engagement distances far beyond what standard M855 ball ammunition and shorter barrels could reliably achieve.

The Centurion Arms MK12 Mod 0 doesn't just honor that legacy - it delivers it, component by component, with the uncompromising build quality the Centurion Arms name demands. Whether you're a collector chasing historical authenticity, a precision shooter demanding a purpose-built DM platform, or an operator who knows exactly what this rifle represents - the M12 Mod 0 is ready.
