Abstract: A muzzle flash simulator for use in an airsoft gun, comprising an internal passage, a detector, a controller, and multiple illuminating components. In response to a projectile passing through and away from the internal passage, the simulator will be triggered and flash multi-color lights on a projectile passage in front of the simulator. When each color light is illuminated on the moving projectile at a specific intensity at specified time periods, because of an afterimage phenomenon of the human eye, the surface of the moving projectile reflects the corresponding color and leaves a multi-layered light-trail accordingly.

Abstract: A toy grenade, designed for launching large numbers of plastic BBs at once, consists of a cylindrical shell with an O-ring interface. The cylindrical shell has circumferentially angled guide portions that allow the O-ring to flex inwardly when moved towards the remote ends. As a result, users can safely unload all the BBs if they wish to do so.

Abstract: A muzzle flash simulator for simulating the visual effect of muzzle flash of the real firearms, configured to illuminate projectiles passing away from an internal passage, includes multiple illuminating components and multiple combinations of sets of instructions for each one of the illuminating components at indicated time periods, to create various beam effects in front of the internal passage.
