Barrett MRAD Barrel Conversion Kit Features The Barrett MRAD Barrel Conversion Kit is built around a 26 inch fluted barrel chambered in .300 Norma Magnum with fluting that trims weight while helping dissipate heat during extended strings of fire. A 1 in 8 twist rate stabilizes the heavier longer bullets typical of .300 Norma Magnum match and hunting loads giving the barrel the right spin rate for long range accuracy. A matching bolt head is included so headspace and function are correct for the new chambering without additional fitting. The included Barrett brake tames recoil on the magnum cartridge keeping the rifle controllable for fast follow up shots at distance. Because this is a complete conversion rather than a bare barrel the kit also includes a 10 round magazine sized to .300 Norma Magnum so the rifle is ready to run as soon as the components are swapped in. Protection for transport and storage comes from a ZCORR anti corrosion bag housed inside a dedicated Barrett branded carrying case guarding the stainless steel barrel against moisture and handling damage. Earlier model MRAD rifles may require the large breech to small breech conversion kit before this barrel kit can be installed. The Barrett MRAD Barrel Conversion Kit gives MRAD owners a straightforward path to adding .300 Norma Magnum capability to a rifle they already own.
