Mark V Hunter Features The Hunter's stock features a flat-bottomed forend, ambidextrous palm swells, and aluminum pillar construction. Threaded 1/2x28 for use with a suppressor or brake, the barreled action is sealed under a shell of Cobalt Cerakote, shielding it from the elements. A deeply-fluted bolt with removable knob not only trims a little weight and helps clear dust and debris, it also reduces the bearing surface within the action resulting in smoother operation.
