The weight has a front extension inserted through the lower receiver of the toy riffle and connected to the rear end of the piston spring at the rear side of the piston so that the component parts of the backlash vibration structure doe not touch the piston during movement of the piston. An adjustment knob is provided at the buttcap spacer for adjustment of the reaction spring to adjust the level of the backlash vibration.
