Product Description

The Defender-ST™ Enclosed Solar Micro Red Dot is a tough, adaptable micro-optic built for pistols, shotguns, and carbines. Its fully enclosed, 7075 aluminum housing protects the emitter from impact and the elements while battery + solar power deliver extremely long runtime. Multi-reticle customization, a large viewing window, and unlimited eye relief make it fast to acquire and engage targets in any lighting. With motion activation, button lockout, and a side-load CR2032 battery, the Defender-ST is purpose-built to stay on target in the harshest conditions.

Key Features

  • Enclosed Aluminum Housing: Durable 7075 aluminum protects against debris and moisture.
  • Multi-Reticle: 3 reticle options with 12 brightness settings (10 daylight, 2 night-vision).
  • SOLAR with Auto D-TEC Technology: Automatically uses solar or battery power based on light conditions.
  • Large Viewing Window: Fast target acquisition and wide field of view.
  • Aspherical Lens: Distortion-free sight picture and truer colors.
  • Fast-Rack™ Textured Grip: Aggressive texture for racking the slide off any surface.
  • Motion Activation + Auto-Shutoff: Motion turns the unit on; 10-minute auto-shutoff saves battery life.
  • Button Lockout: Prevents accidental brightness changes during use or transport.
  • Side Load Battery: Easy CR2032 changes without removing the optic or re-zeroing.
  • Ruggedized: Waterproof, fogproof, and shockproof for extreme environments and recoil.

Multi-Reticle

The Defender-ST multi-reticle offers three reticle options and 12 brightness settings (10 daylight, 2 night-vision) to quickly adapt to diverse shooting situations.
