The HS Precision rifle stocks are built one at a time from the highest quality raw material. HS Precision starts by CNC machining the aluminum bedding block. Every stock produced will have an aluminum bedding block that is machined specifically to the dimensions of the Howa Barreled Action. The aluminum bedding block is then placed into a mold. Both sides of the mold are hand laminated with Kevlar, fiberglass and carbon fiber. An abundant amount of these materials are added for strength and durability. Next the mold is injected with a proprietary mixture of a dense polyurethane foam material. This gives the general shape and design of the stock. The rest of the time is spent hand finishing the stock to ensure a perfect fit and finish. Features: Sub-MOA guarantee Life time warranty
