The Micro T-1 is a 1X (non magnifying) parallax-free optic that features a 2 minute of angle (MOA) red dot for fast target acquisition. No tools are required to zero the sight, as the top of the caps covering the windage and elevation screws fit directly into holes on the adjustment screws to make the adjustment. The Micro T-1 is waterproof to 25 meters (80 feet) and tough enough to stand up to the worst field conditions. Optimized for use with all generations of night vision devices, the Micro T-1 features a manual adjustment switch with 6 night vision compatible settings and 7 daylight settings (including one extra bright setting for use in desert sunlight or with laser protection filters). Aimpoint s state-of-the-art ACET diode technology allows the Micro T-1 to operate continuously for over 5 years on a single CR-2032 battery. The Micro T-1 is a very exciting tactical optic not just because of its small size, but also due to its extreme versatility. Not only is the Micro T-1 a full-featured stand-alone combat optic, it can also be mounted on top of other magnifying optics, giving the operator dual capabilities to engage targets in a CQB situation as well as at longer ranges. Now, everyone can have the speed advantage of a red dot sight, no matter what type of weapon or primary optic they are carrying.
