Designed for the USMC as a supplemental round to M855 green tip with more desirable terminal characteristics. Made for duty use. Designated as MK318 MOD-0 the round was designed as a barrier defeating round with superior penetration and better ballistic stability when shooting through glass, car doors and other barriers where other rounds simply bounce off. It was engineered after the Marine Corp identified issues with the M855 round. MK318 utilizes a 62 grain open tip boat tail match bullet with a lead core and reverse copper jacket creating the open tip. Very, very accurate and critically lethal.
These are not offered as a component to the public and is increasingly hard to find.
