Description
Hardened stainless steel guide rod won’t break or flex and bind the spring like the factory plastic rod. Helps prevent cycling problems, improves reliability and overall performance. Features a captured, ISMI chrome silicon flat spring that’s heat-treated, shot peened, and calibrated to the factory-spec 17 lb. weight. Steel Allen head screw and washer secure the spring to the rod, yet enable easy disassembly for spring replacement.
