  • Laser pistol
    Patent number: 6146141
    Abstract: The present invention relates to a laser pistol characterized in that the laser (1) is inserted into the barrel and electronically triggered (13). In order to have a true shooting sensation, a compressed air cylinder (28) causes the pistol carriage to recoil. The cylinder (28) is controlled by a changeover valve (24') which is actuated by a control element coupled with the trigger (9). When working, the changeover valve (24') causes a compressed air loader (17') to connect with the cylinder (28).
