ABSTRACT:
A double set trigger for a rifle is disclosed, consisting of a sear, a middle lever, a firing trigger, a set trigger, a catch for the set trigger, and a lever to sense the presence of the rifle bolt. The double set trigger has two springs, one for a light pull and one for a heavy pull. The force from the heavy pull spring is applied through the set trigger. The catch withholds the set trigger from the firing trigger for a light pull; the catch may be released by a second pull on the set trigger. The bolt sensing lever will release the set trigger if the bolt is withdrawn. A counterweight locates the center of gravity of the firing trigger concentric with the pivot point of the firing trigger.
