Designed for pistols and also compatible with AR platform rifles, the Riton Optics 1x X3 Tactix PRD Red Dot Sight allows for fast, both-eyes-open target acquisition in close-range tactical and competition use. The sight comes with a Picatinny rail mount that can be removed to reveal an RMR-style base. The 3 MOA dot can be set to one of six brightness levels with off settings in-between and 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 MOA per click, with total elevation and windage adjustment ranges of 45 MOA. One CR2032 battery is rated for 40,000 hours of life, and the four-hour auto shutoff helps conserve power. If you do need to install a new battery, the top-loading mechanism makes it easy.Optical Performance Magnification: 1x Fully multi-coated, anti-scratch optics Unlimited eye reliefReticle Red dot reticle: 3 MOA 6 brightness levels with off settings in between Parallax-free to 50 yards 45 MOA windage and elevation adjustment range 1 MOA impact point correction Four-hour auto shutoffConstruction Removable Picatinny mount and RMR-style base 6061-T6 aluminum housing Nitrogen purged, waterproof and fogproof Recoil resistant, tested to 1200 Gs Runs on one CR2032 battery, 40,000 hours runtime Top-loading battery compartment
