Abstract
Abstract Disclosed is a trigger for rifles and similar firearms, which trigger is provided with an arresting element that permits the easy positioning of the trigger into the desired arresting notch of the trigger support provided in the body of the rifle. Three embodiments are presented of variants of the invention, in which essentially, a plurality of arresting notches are made in the trigger support, either beneath it or laterally thereto, and a spring-loaded arresting element with a manually operated tooth is forced into mating engagement with the notches for a constant contact of the two parts of the device.
