Weatherby Mark V Backcountry Guide 240 Weatherby Magnum BSF Carbon/Graphite Black Cerakote/Backpack Camo Left Hand Bolt Action Rifle - 24in - The Mark V Backcountry Guide 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 Guide series utilizes shorter BSF Carbon Fiber barrels making it easier to run suppressors and navigate in thick, rugged terrain. FEATURES: BSF Carbon Fiber Barrel: BSF Barrels use carbon fiber in a way that no other carbon barrel manufacturer does, leading to unmatched accuracy and heat dispersion properties.; Tensioned Barrel: After BSF turns down a 416R stainless steel match barrel they sleeve it with carbon fiber and load it under tension. Because it's under tension, as the barrel heats up it keeps the rifling straighter, resulting in a stiffer, more rigid barrel. Most competitors use a wrapping method that has been proven to trap heat and cause delamination.; Cooler Barrel - Consistent Groups: With BSF's proprietary method, 95% of the carbon fiber does not touch the contoured barrel, creating air gaps and allowing air to foil around the steel and cool the barrel faster. The high-quality carbon fiber is designed to move at the same expansion rate as the 416R stainless steel resulting in a vibration dampening effect. What does that mean? It means the carbon fiber absorbs the shock and vibration allowing more consistent groups.; Spartan Precision Gunsmith Adaptors: Spartan Precision's Gunsmith Adapters are designed for hunters who want the ultimate lightweight attachment systems. The gunsmith adapters feature the MagnaSwitch Attachment System that uses rare earth magnets to quickly and securely swap your bipods. These are featured withi
