Wolff Gunsprings SKS Reduced Power Hammer and Sear Spring Kit

Wolff's Rifle Performance Pak for the SKS, sold by distributors as the SKS tune up kit. It holds two springs: one reduced power hammer spring rated at 27.5 lb (stock SKS hammer springs run 33 to 36 lb) and one reduced power sear/magazine latch spring. Wolff sells the pair to improve the SKS trigger.

Wolff lists it for Chinese and Russian variant SKS 7.62mm rifles. A lighter hammer spring hits primers with less force, so test it with the ammo you shoot, especially hard military primers.
