Introducing Barska's smallest mounted laser to date. The Micro GLX Laser Sight System delivers the strength and durability needed to withstand the shock of rapid-fire recoil. The Micro GLX Laser features cutting edge design technology in a small yet powerful package. The standard weaver compact mount allows this laser sight to be securely mounted to a variety of compact and sub-compact handguns that are equipped with a fore end rail. The ambidextrous tap on/off button is placed exactly where your trigger finger will be when drawing your firearm. This model emits a highly visible laser beam, which produces light of 532 nm in wavelength for amazing visibility. Windage and elevation adjustments can be made externally on the body of the laser. Operates on one CR-2 Lithium battery (included). Backed by Barska's One-Year Laser Warranty.
