Equally at home on duty and at the range, the Vortex Defender-ST Micro Green Dot Sight is designed to be tough, fast, and accurate in competition shooting. The 3-MOA dot illuminates in eight daytime brightness levels and two that are compatible with night vision gear. The aspherical lens offers a distortion-free, virtually parallax-free sight picture with unlimited eye relief. Aggressive texture on the face of the sight allows you to rack your slide against any surface. The Defender-ST is motion-activated and shuts off automatically after 10 minutes. The battery installs on the top, so you don't have to re-zero your optic when replacing it (which won't happen often, considering the battery's 25,000-hour lifespan.)
