Barska's GLX Laser Sights are designed with an accessory rail mounted conveniently under the laser. The T6 aluminum body allows for the GLX laser sight to provide a strong, stable platform to mount accessories to its integrated military standard Picatinny rail. The GLX Laser Sight is extremely versatile in its mounting options. The built-in mount is a Weaver-style compact mount with a stabilizing cross bar insert for added support. The compact mount allows secure mounting to the shortest of rails on handguns and rifles. This model emits a highly visible laser beam that produces light of 532nm in wavelength powered by a CR123A battery. The GLX includes an integral Weaver-style mount, a momentary activation switch and is covered by a 1-year factory warranty.
