The Alpine ST is built on Weatherby's newest bolt-action rifle platform, the Model 307. Meant to complement the historic Mark V and Vanguard lineups, the Model 307 action is a 2-lug, fully cylindrical action compatible with many aftermarket accessories. Model 307 is designed to accommodate the vast offerings of stocks, triggers, rails, and mounts that exist in today's marketplace. Weatherby teamed up with PEAK 44 to produce an ultra-light rifle that can own the range and dominate in the field. The PEAK 44 Bastion stock weighs in at 24 ounces and uses a proprietary 3D-Hex recoil pad to reduce the effects of recoil. The lightweight, spiral fluted barrel delivers unmatched accuracy and comes with Weatherby's recoil-reducing Accubrake ST.
