Really cool factory laser system for 91 types. Mounting hardware, battery set in special pistolgrip. Even has fliptype lens. Shown with trigger pack in picture. That's available separately. Laser itself made by Laser Products Inc. dated 3/86. Try and find one of these anywhere else. More pix available to serious buyers. I do not know the voltage so I've not charged it up. It's pretty cool, though. $250 is what I'm asking for this rare bird. Respond through email, please. Thanks.
