The X-Bolt Pro is just about as close to a custom rifle as it gets. What classifies it as "semi-custom" 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 also filled with a noise-dampening foam. In addition to the carbon fiber stock, this rifle includes a number of upgrades. The sporter contour barrel is fluted and capped with a Sporter Recoil Hawg that tames felt recoil up to 76% for more comfortable shooting. A thread protector is also included.
