Browning is delving into semi-custom rifle production with the new X-Bolt Mountain Pro. What classifies the X-Bolt Mountain Pro as a "semi-custom rifle" is the level of specialized finishing touches and higher end construction above the already top-tier X-Bolt family of hunting rifles. First, the X-Bolt Mountain Pro features a true carbon fiber stock — now lighter than previous versions — making it lightweight and rigid. The stock is filled with a noise-dampening foam. Additionally, the Cerakote finish on the stainless-steel action and barrel is also on the exterior of the stock for added protection. The Tungsten hue mutes the color of the stock for better concealability. The barrel features a new proprietary lapping process to provide consistent accuracy and easier bore cleaning — avoiding the need for a time-consuming break-in process. Other features include a spiral fluted bolt and bolt knob, threaded muzzle with our new Recoil Hawg muzzle brake that reduces felt recoil up to 77% (depending on caliber), effectively taming your favorite magnum cartridges.
