Weatherby Model 307 Alpine MDT 6.5 Creedmoor Carbon Grey Cerakote Bolt Action Rifle - 22in - Engineered for precision. Built for performance. The Alpine MDT Carbon is Weatherby's most advanced bolt-action rifle yet-built on the all-new Model 307 platform. Designed to seamlessly integrate with the latest aftermarket upgrades, this 2-lug, fully cylindrical action gives you complete customization flexibility with stocks, triggers, rails, mounts, and mags. Crafted in partnership with MDT, the ultra-lightweight carbon fiber chassis includes a foldable buttstock, reducing overall length by over 9in when collapsed-perfect for backcountry treks or tight storage. Its shorter BSF carbon barrel isn't just compact-it delivers pinpoint accuracy and comes equipped with the Accubrake DST, Weatherby's proprietary Directional Self-Timing muzzle brake. Whether you're dominating the range or taking the shot of a lifetime in the field, the Alpine MDT Carbon is purpose-built to perform. The Alpine MDT Carbon is compatible with most after-market 700 platform parts, making it the most open platform in the Weatherby line-up. Proudly built at the headquarters here in Sheridan, WY. Thread Pitch: 5/8 x 24 ; Tension 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
