Barska's new GLX Laser Sight features external riflescope style windage and elevation adjustments for quick, high precision targeting. The 3rd Generation GLX laser makes zeroing in your laser a quick and easy process, simply unscrew the protective adjustment caps to access the finger adjustable turrets to move the laser dot up and down or left to right. The green laser produces light of 532 nm in wavelength. Powered by a high capacity CR123A lithium battery (1 battery included) the GLX can emit a high intensity green laser beam constantly for accurate targeting. The new tactical design integrates a tactical edged bezel into the strong T6 aluminum body for added protection. The new diamond cut exterior grip improves the mounting capability of the Picatinny 1" mounting ring included with the laser sight. The GLX Laser comes complete with a continuous push button on/off cap, momentary long cable switch, 1" Picatinny ring with a stabilizing cross bar insert for added support and one high capacity CR123A lithium battery.
