The Burris AR-1X optic is designed for both eyes open shooting. Featuring the Ballistic CQ-1X reticle, it is intended for fast-action shooting in competitive or tactical situations. The circular center provides ultra-fast engagement at close distances. Easy to see reticle hash marks provide trajectory compensation up to 600 yards. The black reticle is etched into the prism so that the optic can be used, even without battery power. Multi lens coatings maximize glare resistance and low light performance. The sight is also night vision compatible. Ruggedly constructed to withstand extreme conditions; it is fogproof, waterproof, and shock resistant
