Browning is delving into semi-custom rifle production with the new X-Bolt Pro rifles. What classifies them as  "semi-custom rifles" 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 Pro models feature a true carbon fiber stock making it extremely lightweight and rigid. The stock is filled with a noise-dampening foam. In addition to the carbon fiber stock, this rifle includes a number of uprades. At the end of the skip fluted, heavy sporter contour barrel resides the new Recoil Hawg muzzle brake that tames felt recoil up to 77% for more comfortable shooting.
