Patent ID: 11959719

Abstract:
Pneumatic simulator for an open bolt firearm including an actuator group having a stationary piston and a moving bolt. With each simulated firing cycle producing a firing event, the spring actuates moving bolt toward stationary piston such that the activator unseats a valve located in the stationary piston. Unseating the valve allows regulated compressed gas to exit a high pressure reservoir located in the firearm magazine well which drives the moving bolt back against the spring to complete a firing cycle. Subsequent firing cycles will continue automatically as long as the shooter keeps the trigger depressed. A tension rod, and laser also may comprise the simulator assembly. A nut may be used to secure the tension rod and laser. A laser cable may be used to electrically connect laser to a firing event signal generator. The firing event signal generator may include a magnet located in the moving bolt and a pickup positioned in the stationary piston. With each firing event, the magnet is moved adjacent the pickup which evidences a firing event which generates a signal from the pickup to the laser over the laser cable. The laser then generates a pulse of light which strikes a target to mark a point of impact resulting from the firing event.
