摘要： A pneumatic counting apparatus for a weapon simulator having a magazine including a compressed gas storage reservoir including a toothed element adapted for articulation within the magazine. The toothed element including a plurality of steps, a first face and a second face. A wheel actuator including a lever for engaging the steps of said toothed element so as to articulate the toothed element. The toothed element including a pneumatic passage there through. A pneumatic branch is in communication with the gas storage reservoir and terminating at a sealed passage adjacent the first face of the toothed element. A pneumatic bridge extends between a pressure chamber and a pneumatic gate positioned adjacent and in selective pneumatic communication with the pneumatic passage on the second face of the toothed element. The pneumatic passage is adapted for selective communication of compressed gas between the passage and the pneumatic gate. A slide catch lifter is in pneumatic communication with said pressure chamber.

摘要： 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.

摘要： A training weapon which is quickly and easilyassembled from a standard weapon without requiring any physical modification (alteration) of any component of the standard weapon. A few components of the standard weapon are removed and replaced by components of the invention. This replacement does not exceed skill level beyond a standard field-strip procedure of the particular weapon. Action of the training weapon is of the same character as the action of the standard weapon, while developing trainee's responses to the substitute firing action, and at the same time improving trainee's skill, all without the use of live ammunition. Installed components include means of cycling the the weapon's mechanism thus simulating recoil using compressed gas, optional laser pointer activating a target, and a replacement magazine including source of electricity and an electronic control circuit and operable with a gas passage unit. Weapon's original trigger mechanism remains unchanged and is utilized to initiate the substitute firing cycle.

摘要： A shock activated laser module for simulated shooting transmits a brief laser beam to mark a point of impact. The module includes a housing, an electro-optical member, a stored energy member and a retaining cap securing the electro-optical member and stored energy member in the housing. The laser module housing is selectively attached in combination to any one of a simulated firearm barrel, a simulated firearm gas reservoir, or to an actual firearm for dry-firing practice.
