The Timney Ruger American Centerfire Gen 1 Two-Stage Trigger (brand part no. 645C) is a replacement trigger fitted specifically to the first-generation Ruger American Centerfire rifle, distinct from Timney’s Gen 2-fit version. It uses a two-stage design, letting a shooter take up a light first stage before a crisp, heavier second-stage break, with the first stage breaking at 8 ounces to 1 pound and the second stage at 1 to 2 pounds. The housing is built from alloy with steel internal parts and finished in blued. For original Ruger American owners who want a genuine two-stage feel over the factory trigger, this rifle trigger is fit specifically to that generation.
