ABSTRACT:
A trigger arrangement for an automatic weapon with switch-over between continuous firing and single-shot modes includes a hammer, a breechblock, a latch, a pivotably mounted trigger, and a firing lever. In the single-shot mode, the firing lever engages the hammer and retains it in tension while the trigger is depressed. When the continuous firing mode is selected, the firing lever is moved to an inactive position and retained by an engaging element. The engaging element is preferably a slider which is controlled by a safety and firing cessation roller that is actuated by an operating lever.
