Winchester Model 70 Extreme Weather SS/Synthetic .300 Win Mag Bolt-Action Rifle with Muzzle Brake

The Winchester Model 70 Extreme Weather is built for hunters and shooters who demand performance regardless of conditions. Chambered in hard-hitting .300 Winchester Magnum, it pairs a stainless steel barrel with a weather-resistant synthetic stock to stand up to rain, mud, and temperature swings that would compromise lesser rifles. The controlled round feed action—the hallmark of the Model 70—delivers the reliability serious hunters trust in the field. A muzzle brake is included to tame the magnum recoil and keep follow-up shots on target.
