The AAT5G Green Laser Designator from Sightmark is an advanced, accurate and powerful tactical-laser red-dot sight with easy base x/y windage and elevation adjustment. This unique sight has a visibility range of up to 50 yards in daylight and 2,640 yards at night, but uses very little power in its operation. The quick target acquisition and precision accuracy of this advanced laser designator make it perfect for rapid fire or moving targets. The built-in Weaver mount ensures the Brick can fit onto the widest variety of weapons. Sightmark’s AAT5G is lightweight, compact, shockproof and covered by Sightmark’s limited lifetime warranty.
