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. You'll also find that the barrels on the Alpine MDT Carbon are shorter than our traditional offerings. The BSF Carbon Barrel Delivers unmatched Accuracy and comes with Weatherby's Accubrake DST (Directional Self-Timing Brake). Threaded Barrel: 5/8 x 24 ; 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 - Consistant 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.; Guaranteed Sub-Moa Accuracy - All Model 307 rifles are guaranteed to shood a 3-shot group of .99in of leass at 100 yards (SUB-MOA) from
