Vortex Defender ST Enclosed Solar Micro Red Dot
Price includes VAT
Tough, adaptable, ready for anything—the Defender-ST™ Enclosed Solar Micro Red Dot gives you a no-quit edge on pistols, shotguns, and carbines. Its ultra-rugged, fully enclosed design protects the emitter against impact and the elements, keeping you on target in any condition.
Description
Battery and solar power keep it running as long as you do, while multi-reticle customization let you quickly adjust and lock on targets in any light—day or night—across any platform.
Features
- Enclosed Aluminum Housing - Durable 7075 aluminum enclosed housing protects against debris and moisture.
- Multi-Reticle - Quickly adapts to diverse shooting situations.
- SOLAR with Auto D-TEC Technology - Detects light conditions to automatically draw power from solar or battery as needed.
- Large Viewing Window - For fast target acquisition and wide field of view.
- Aspherical Lens - For a distortion-free sight picture and truer colors.
- Fast-Rack™ Textured Grip - Aggressive texturing on face of optic for racking slide off any surface.
- Motion Activation with 10 Minute Auto-Shutoff - Automatically activates with motion while 10 minute auto-shutoff saves battery life.
- Button Lockout - Prevents accidental brightness adjustment during use or transport.
- Parallax Free - All red dots 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.

- Side Load Battery - Easy battery changes without having to rezero your optic.
- Waterproof - Designed to withstand harsh weather conditions.
- Fogproof - Designed to withstand a wide range of temperatures.
