The Ruger No. 1 is a single-shot rifle with a Farquharson-style hammerless falling-block action, introduced and manufactured by Sturm, Ruger & Co. since 1967.[4] An underlever lowers the breechblock to allow ammunition loading and also cocks the rifle. Lenard Brownell, commenting on his work at Ruger, said of the No. 1: "There was never any question about the strength of the action. I remember, in testing it, how much trouble I had trying to tear it up. In fact, I never did manage to blow one apart."[5]
