Premium Features

  • Perfect for a 50/200 yard zero with the red dot, with a 7-yard holdover with the bottom crosshair
  • A wide 25mm multicoated lens ensures a crystal-clear view of your target, and a broad field of view looking down the sight
  • 2 night vision compatible settings with 9 daylight settings, with a battery life up to 50,000 hours on the lowest daylight setting
  • Compatible with AT3’s RRDM and 4xRDM Magnifiers for great clarity at long range

Risers for Any Application

  • Using the included risers and spacer, get Absolute Cowitness or Lower 1/3 Cowitness for your AR15
  • Also great for AK rifles, CZ Scorpions, Tavor and X95, as well as many other modern shooting platforms

Tough and Protected

  • Optimized for the AR, but tough enough to withstand harsh recoil from shotguns and high caliber rifles
  • Included transparent lens caps keep your lenses protected while providing a complete look at your target
  • Forged aluminum housing is our toughest yet, with shockproof and waterproof circuitry inside
  • Windage and elevation knobs are flush-fit, with no need for protective caps that get lost

My Red Dot Scope came very quickly after I placed my order. Packaged very well and I can't wait to get to the range with it on my rifle.
