The AMP Tactical Green Laser Kit comes with all the hardware for mounting this compact green laser to any picatinny/weaver rail system. Adjustable for windage and elevation, this laser can be zeroed in for accurately firing on the run or from the hip. A powerful 532nm green laser can be seen up to a mile away at night, and at 20 time the brightness of a traditional red laser, can be seen in broad light at closer distances. Powered by a single CR123A battery (included) for up to 4 hours of continous use and constructed from durable 661 T6 Aircraft Grade aluminum, this green laser is build to last. The kit also includes a 10" cable with pressure switch, mounting rings and hexhead tools.
