Abstract
A tripping mechanism is disclosed for the conversion of automatic rifles of the so-called closed-bolt type to rifles of the open-bolt type. The components of the mechanism are premounted within a box-like support which is readily insertable in the trip box of a conventional automatic rifle. The mechanism includes a trigger, a trip block for arresting the bolt carriage in the open, armed position, a connecting rod attached to and displaceable with the trigger and cooperating with the trip block during the disengagement of the bolt carriage from its blocked position, a safety bolt operating also as selector of the firing mode by cooperating with a lever, a lever for engaging the trigger during the automatic, continuous firing mode, and, finally, a safety block for arresting the bolt carriage in the event of accidental disengagement from the trip block.
