Weatherby Model 307 Alpine MDT 300 Weatherby Magnum Graphite Black Cerakote Bolt Action Rifle - 28in - The Alpine MDT 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, mounts, and magazines that exist in today's marketplace. Weatherby teamed up with MDT to produce an ultra-light chassis rifle that can own the range and dominate in the field. The carbon fiber chassis features a foldable buttstock and when collapsed cuts out over 9in of total length making it a great compact option.
