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. BARSKA has designed the GLX compact laser sight to withstand extremely high impact shock generated by large caliber rifles and hand guns. The GLX laser finds itself equally at home on a rifles picatinny rail forends as it is on a handguns bottom rail. The GLX compact laser has a easy accessible on/off slide switch ideal for hand guns.
