Browning is delving into semi-custom rifle production with these 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 - now lighter than previous versions - 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. Most obvious is the great-looking, durable and highly protective Cerakote Carbon Gray finish. At the end of the skip fluted, sporter contour barrel resides the new Recoil Hawg muzzle brake. The Recoil Hawg tames felt recoil up to 77% for more comfortable shooting. A thread protector is also included.
