The Alpine ST is built on Weatherby's latest bolt-action rifle platform, the Model 307. Designed to complement the historic Mark V and Vanguard lineups, the Model 307 action is a 2-lug, fully cylindrical design compatible with many aftermarket accessories. It is meant to support the wide range of stocks, triggers, rails, and mounts available today. Weatherby partnered with PEAK 44 to create an ultra-light rifle that performs well on the range and in the field. The PEAK 44 Bastion stock weighs 24 ounces and features a proprietary 3D-Hex recoil pad to help reduce recoil. The lightweight, spiral-fluted barrel offers exceptional accuracy and is equipped with Weatherby's recoil-reducing Accubrake ST.
