An optical device controller, for controlling an optical device positioned in a barrel-like portion of an imitative gun facing the outside through a muzzle-like opening of the barrel-like portion. An operation controlling portion is provide for shifting the optical device from an inoperative condition to an operating condition in response to movement of a trigger-like portion, a movable valve provided on a gas leading passage for controlling the gas leading passage to be open in response to the movement of the trigger-like portion, and a sliding member having a pressure receiving portion formed therein positioned at the back of the barrel-like portion for receiving pressure of the gas coming through the gas passage formed in the gas passage forming portion and the gas leading passage which is controlled to be open by the movable valve and provided to be moved back along the barrel-like portion with the pressure of the gas acting on the pressure receiving portion.

An action reciprocating structure of a toy gun an action part and a gear box of a loading mechanism, of a toy gun, wherein the action part is located at a top of the toy gun, the gear box is located at a bottom of the toy gun, and a reciprocating mechanism is located between the action part and the gear box. The reciprocating mechanism includes a pump mechanism, connected to a reciprocator which is provided with an elastic member and a small piston having an air-tight ring therein. When the pump mechanism is filled with gas to push an air-tight piston in the pump mechanism, it also pushes the elastic member and the small piston of the reciprocator, such that the action part which is connected on the small piston can achieve an emulated shooting effect of a reciprocate movement, at the same time.

A laser sighting device for a firearm and a method for mounting a laser sighting device on a firearm. A laser sighting device for a firearm comprises a holder adapted to attach to the handgrip of the firearm such that the firearm may be held in a firing position by the handgrip with the device installed thereon, the holder including a first compartment for receiving a laser and holding the laser so as to propagate a beam of light substantially in the muzzle direction of the firearm, and a second compartment for receiving a battery to power the laser, a switch for activation of the laser by the user's hand holding the handgrip in firing position, and an electrical circuit disposed within the holder for interconnecting a laser disposed in the first compartment, a battery disposed in the second compartment and the switch.

A bolt locking assembly for a weapon simulator, the weapon simulator having a bolt affixed to a firearm housing providing recoil to the user. The bolt is connected to a piston housed in a piston chamber inside the housing. A gas supply provides a compressed gas or fluid into the piston chamber to generate movement and recoil of the piston. After the weapon simulator has been fired a predetermined number of times, the bolt locking assembly will obstruct operation of the bolt and piston. The bolt locking assembly includes a lock actuator port engaging the piston chamber, a locking apparatus positioned within the housing proximate the bolt, and a lock channel between said lock actuator port and said locking arm, wherein the lock channel directs gas to said locking apparatus to actuate said locking apparatus and fix the bolt in place.
