Barrett MK22 Barrel Conversion Kit Features The Barrett MK22 Barrel Conversion Kit swaps a Barrett MRAD/MK22 into 7.62 NATO in minutes giving owners a second proven chambering on the same trusted action they already shoot. The 20 inch fluted barrel is cut with a 1:8 inch twist to stabilize a wide range of 7.62 NATO bullet weights and the fluting sheds weight while helping the barrel dissipate heat during strings of fire. A matched bolt head ensures correct headspacing for the new caliber and earlier MRAD rifles may require an additional large-to-small breech conversion kit to complete the swap. The Coyote Brown Cerakote finish resists wear and corrosion across repeated field use. Included with the barrel and bolt head are a 10-round magazine and a ZCORR anti-corrosion bag so the whole kit ships ready to store or transport between range trips. The ZCORR bag actively protects the barrel and components from moisture and rust during transport or long-term storage between uses. Swapping calibers on the MRAD platform keeps a shooter s investment in optics stock setup and trigger feel intact while adding real versatility. This conversion kit is a straightforward way for MRAD/MK22 owners to add capability without buying an entirely new rifle for sale at GrabAGun.
