Proudly made in the USA and built for Heavy-duty use with the tightest tolerance controls to provide the most secure fit and function. The combination of the Mil-spec stock and Mil-spec extension tube along with the built-in rubberized butt pad and a slanted cheek rest enhances shooting stability and promotes consistent firearm control. The extension tube is precision machined from aircraft grade aluminum with rolled threads, and anodized for best corrosion and wear resistance.&nb
