BARSKA's GLX compact mounted laser sight is 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 compact laser sight is extremely versatile in its mounting options. The built-in mount is a weaver standard 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 powerful red laser sight emits a highly visible red laser beam that produces red 635 nm wavelength light which is highly visible to the human eye. BARSKA has designed the GLX compact laser sight to withstand extremely high impact shock generated by large caliber rifles and handguns. Backed by BARSKA's One year warranty.
