New Marine Corps Sniper Rifle Achieves Full Operational Capability

The Marine Corps Mk22 Mod 0 Advanced Sniper Rifle has achieved full operational capability, completing its upgrading ahead of time. Barrett Firearms manufactures the rifle, which replaces the old Mk13 Mod 7 and M40A6 sniper rifles and provides improved range, versatility, and logistical efficiency.

The Mk22 has a modular design that allows Marines to swap between three calibers—7.62mm,.300 Norma Magnum and.338 Norma Magnum—based on mission needs. With an effective range of 1,500 meters, it outperforms its predecessors, including the M40A6's 800-meter range. In addition, the rifle's 10-round magazine provides more firepower than prior models' five-round capacity.

On November 19, the Marine Corps Systems Command in Quantico, Virginia, declared that all Marine infantry and reconnaissance units and training schools were now equipped with the Mk22. Marines have received extensive training to master the system, which consists of a bipod, suppressor, and a 7x35 Precision Day Optic.

"The ability to conduct caliber conversions at the unit level and consolidate to a single rifle improves operational efficiency and reduces logistical burden," said Kevin Marion, a logistics management expert. Unlike its predecessors, the Mk22 allows for fast barrel replacement, ensuring mission readiness even if a barrel fails.

The Mk22, initially created by the United States Special Operations Command, reflects decades of sniper system developments. While the Marine Corps has acquired 250 rifles, the Army is also switching to the Mk22, with plans to purchase 2,800 by 2026.

This improvement marks a substantial advancement in sniper technology, allowing Marines to perform more successfully in various combat settings.
