This green laser option replaces the red laser/light unit of UTS-15 shotgun systems. The new unit features the same operation with the addition of a new position allowing for light-only or simultaneous light and laser activation. The green laser/light unit is specially designed to slide into the barrel retaining tube in the lower stock, where it is held in place by the barrel-retaining cap. The unit comes complete with a drill jig, an Allen wrench and mounting screws for easy installation of the three-position rotary switch. The unit is powered by two CR123A lithium batteries, which are easily accessible for quick battery changes. For more information, visit utas-usa.com.
