Incorporating the very latest in state of the art composite construction techniques, fiberglass rifle stocks from Borden Rifles have become the standard by which all synthetic stocks are measured. Each current model of Rimrock stock is a custom design by Jim Cloward, Callum Ferguson and/or Jim Borden. They are elegantly crafted in a classic style to precisely fit the barreled action and shooter. Rimrock stocks are a one piece, seamless fiberglass shell reinforced with solid fiberglass cross bolts and pillars, and filled with a sound absorbing and vibration dampening rigid plastic foam. The stock is a seamless, pressure molded, high temperature epoxy / fiberglass laminate.
