Murray's SKS Reduced-Power Hammer & Sear Spring Set (Wolff)

The SKS trigger is heavy by design, with a stock hammer spring running roughly 33 to 36 pounds to drive the hammer hard enough for reliable ignition of surplus and steel-case 7.62x39. That spring tension is the single largest contributor to the gritty, heavy SKS trigger pull. Murray's Gunsmithing sells a Wolff reduced-power set that swaps in a 27.5 pound hammer spring and a reduced-power sear spring, the standard SKS trigger job for owners who do not want to replace the entire trigger group.

The lighter hammer spring measurably reduces felt pull weight while retaining enough strike energy for normal commercial and quality surplus ammunition. The reduced-power sear spring smooths sear release. Installation is a bench job: drop the trigger group from the receiver, swap the two springs, and reassemble. The set does not alter sear engagement geometry or reset distance, so factory creep characteristics remain; what changes is the weight, which is the part most SKS owners want fixed first.

At $13.79 direct from Murray's, this is the cheapest meaningful trigger upgrade for the platform and the right starting point before considering a full aftermarket trigger group. Shooters running the lightest surplus primers should confirm reliable ignition after the swap, since reduced hammer-spring tension is the relevant variable for hard military primers.
