Burris

With the Burris AR-1X push-button activation lets you choose between 5 illuminated green, 5 illuminated red or black reticle settings. One lithium battery yields up to 5,000+ hours of service. The black reticle is etched onto the prism, so you can use the optic even without battery power. The easy to see reticle hash marks offer trajectory compensation to 600 yards; lens coatings are maximized for glare resistance; low-light operation; tethered caps and flip up lens covers and is night-vision compatible.
