The barrel is rated for +P or NATO spec ammunition, however, it will need to be paired with a lower that has an appropriate buffer and spring. We would recommend no less than 6.5oz for buffer weight when using the higher pressure ammunition. We do not recommend or warranty the use of +P+ or "Major" loaded ammunition in our barrels.
