This Rossi ’92 Spring Kit is simple enough for the novice to install and yet sophisticated enough for the professional Gunsmith to fine-adjust for individual guns. The kit includes the following features: Main Spring adjustable to 5 different tensions with approximately 8% changes in spring tension between settings and allows for fine adjusting of mainspring tension for individual rifles and ammunition. Two different strengths of ejector spring to allow the kit to serve both small and large calibers and to allow for individual adjustment. Springs are zinc coated to resist corrosion. Spring ends are closed and ground square to sit flat and square against other parts in the gun. The nylon bushings maintain spring alignment on both ends of the hammer strut, reduce friction, and provide an easy way to adjust the tension without cutting coils. Parts are color coded, and illustrated instructions are included for easy installation.
