NEW WEATHERBY MKV CARBONMARK 257 WBY MAG

Threaded 1/2×28 for use with a suppressor or brake, the Mark V Hunter’s 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. 

Designed to be the world’s strongest action, the Mark V has a signature multi-lug bolt system inspired by the interrupted thread style of lockup. Available in both Standard and Magnum action sizes, the Standard employs a six lug design while the beefier Magnum uses nine locking lugs, enabling these actions to safely chamber the hottest commercially-available cartridges on the market. Other safety features include three rings of steel around the base of the cartridge when it’s in battery, a fully-enclosed bolt shroud and three gas relief ports in the bolt body to vent pressure in the case of an ammunition failure
