The Winchester Model 70 Extreme Weather MB (brand part no. 535242229) is a bolt-action hunting rifle chambered in .264 Winchester Magnum, built for adverse weather with a matte stainless action and a fluted, muzzle-braked barrel. Winchester mounts the action in a Bell and Carlson stock with an aluminum bedding block for consistent accuracy, and the 22-inch barrel carries a 1:10-inch twist rate to stabilize heavier .264 bullets. The adjustable M.O.A. trigger system and a Pachmayr Decelerator recoil pad round out a rifle built for serious mountain and long-range hunting. Among bolt action rifles, this Model 70 Extreme Weather configuration favors hunters who want a weatherproof magnum rifle for tough conditions.
