These are the same stocks we use on our incredibly accurate Summit titanium rifles. Part of that accuracy comes from the high strength and rigidity of the stock. Made from 100% hand-laid Aerograde carbon fiber. Stocks must be bedded at least at the recoil lug and also may need additional fitting for your action and safety. These stocks take 3-5 working days to ship in stock. Backorders take up to 10 weeks to manufacture.
