When it comes to working on firearms, there is no one-surface area or jaw angle that fits every need. From long guns and pistols, to barrels and guide rods, The Smart-Jaws Multi-Fit Sleeves have you covered. These non-marring, thermoplastic rubber-covered jaws accommodate all sizes and shapes of guns and parts to hold them securely without damaging your investment. The flat, but slightly textured area is designed to secure your shotgun, pistol or bolt gun. When working on bolts, barrels or choke tubes, simply reverse the jaws and find the groove that best fits your project needs.
