Vortex Optics Defender-ST Micro Red Dot Sights (3 MOA)

Large Distortion Free Sight Picture. Automatically activates with motion while 10 minute auto-shutoff saves battery life. Daylight bright, illuminated center dot aids in faster centerpoint acquisition in bright daylight conditions. All red dot and holographic sights will exhibit some small amount of parallax. Matching current industry practice, this small amount would be considered "parallax free" and will make a negligible difference in performance. Non-critical eye relief for rapid target acquisition.
