Very hard to find discontinued laser max USA DESIGNED & ASSEMBLED???????????? UNI green rail, mounted laser with oversized ambidextrous left and right switch for gloved hands. Green pulsed beam, fits virtually any firearm with at least 1.75 of rail space. There are 2 batteries (1 set) included, they have been tested and remain virtually unused along with the windage and elevation adjustment key so you can zero the beam to your desired setup. This item came from a store liquidation and does not seem to have ever been used. I have tested it and ensured that it is new and in perfect working condition. If you have any questions or concerns, feel free to message me I will get back to you as promptly as I can. Thank you for looking. Have a nice day.
