Designed for the AR platform, the Riton Optics 1x23 X1 Tactix ARD Red Dot Sight allows for fast, both-eyes-open target acquisition in close-range tactical and competition use. The 2 MOA dot can be set to one of six brightness levels with off settings in-between, and it performs parallax-free out to 50 yards. The view is bright and clear, thanks to fully multi-coated, high-density glass with 99.5% light transmission. Impact point corrects at 1/2 MOA per click, with total elevation and windage adjustment ranges of 72 MOA. The sight comes with a quick-detach, lower 1/3 co-witness mount. One CR2032 battery is rated for 40,000 hours of life.Optical Performance Magnification: 1x Fully multi-coated, anti-scratch optics Unlimited eye reliefReticle Red dot reticle: 2 MOA 6 brightness levels with off settings in between Parallax-free to 50 yards 72 MOA windage and elevation adjustment range 1/2 MOA impact point correctionConstruction Quick-detach lower 1/3 co-witness mount 6061-T6 aluminum housing Nitrogen purged, waterproof and fogproof Recoil resistant, tested to 1200 Gs
