The Mk 22 Advanced Sniper Rifle from Barrett Firearms is now fully operational with the United States Marine Corps. This announcement comes a full year ahead of schedule. Let’s take a look at the Mk 22 system and its features.


Barrett @ TFB:


The Mk 22 is a version of the Barrett MRAD, but it is more than just a rifle. It is a full package that includes barrels and magazines to change between 7.62 NATO, .300 Norma Magnum, and .338 Norma Magnum. No sniper rifle is complete without a scope, and the Mk 317 Precision Day Optic (a version of the Leupold Mk5 HD 7-35x56) is paired with the Mk 22. The deployment kit also includes a shooting tripod and sound suppressor.


If you are curious about the history of Barrett Firearms, our own Austin Rex got the full story from Ronnie Barrett himself. Check out his article here.

From the manufacturer:


“Barrett Firearms Manufacturing Inc. is proud to announce that the Marine Corps Systems Command has achieved Fully Operational Capability (FOC) for the MRAD® MK 22 Mod 0 Advanced Sniper Rifle (ASR) a year ahead of schedule.
The MK 22 represents the culmination of Barrett’s dedication to innovation and collaboration with the Department of Defense. Originally developed through a Special Operations Command contract, the MK 22 transitioned to the Marine Corps via the "Special Operations Forces (SOF) to service" process, with contracting led by the U.S. Army. This seamless interservice cooperation enabled the Marine Corps to achieve FOC a full year ahead of schedule, delivering critical capability enhancements to warfighters sooner.”

    This was probably one of the smartest decisions the DOD could ever make. Sure the multi caliber makes it heavier in the .308 than it could be but buying one base rifle in three calibers and standardizing across all the services particularly in a niche role like sniper rifle.

      You mean other than Infantry battle rifle? Which is its purpose. To arm the infantry with a weapon that out ranges the guys with AKs and Qbz well the guys who are moving boxes keep the M4.
