Other red dots are made for competition. The Defender-XL is built to win. Target to target. Stage to stage. Designed for toughness, speed, and accuracy, it withstands unexpected drops and the rigors of dynamic shooting. The ultra-wide sight window enhances field of view for quicker target acquisition, faster follow-up shots, and greater flexibility in unconventional shooting positions—all positioning you to dominate every round. Red Dot of the Year!

Key Features:

  • Window Size: 25.5mm W x 23.3mm H
  • Large Hard Coated Aspherical Lens: Large Distortion Free Sight Picture
  • Motion Activation With 10 minute Auto-Shutoff: Automatically activates with motion while 10 minute auto-shutoff saves battery life
  • ShockShield: Polymer insert absorbs shock to the 7075 aluminum body protecting it for everyday abuse
  • Fast-Rack Texturing: Aggressive texturing on face of optic for racking slide off any surface
  • Top Mount Battery: Easy battery change without having to rezero your optic
  • 10 Daylight Bright Brightness Settings: 10 Daylight Bright Brightness Settings

  • Waterproof: O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments.
