Timney Replacement Trigger for Ruger American Gen II Centerfire (642C)

The Ruger American Gen II factory trigger is serviceable but heavier and less crisp than most shooters want once they start stretching the rifle out. The Timney 642C replaces it with a self-contained single-stage module that drops in without a gunsmith, arrives set at 3 lb, and adjusts across a 2-4 lb range. Timney offers the 642C in a curved or a straight trigger shoe, and the unit is engineered to work with the Gen 2 three-position safety, so nothing about the factory safe-handling controls changes. It is the cleanest single upgrade for turning a value Gen 2 into a rifle that breaks predictably at the bench.
