Weatherby Mark V Backcountry 308 Winchester BSF Carbon Barrel Bolt Action Rifle - Starting at just 5.1 lbs, the Mark V Backcountry Guide Ti was purpose-built to be the best lightweight mountain rifle on the market. It features Peak 44's Blacktooth carbon fiber stock with Spartan Precision's gunsmithing adapters factory installed. These adapters allow hunters to utilize Spartan's ultra-lightweight accessories. Equipped with an Accubrake ST and 3DHex recoil pad, the Backcountry Guide series manages recoil extremely well even with Weatherby's historic magnum cartridges. The titanium action has an incredible strength-to-weight ratio cutting even more weight than the standard steel action. The Guide series utilizes shorter BSF Carbon Fiber barrels making it easier to run suppressors and navigate in thick, rugged terrain.
