The XPS2-Sage Holographic Sight (Matte Black) from EOTech provides rapid heads-up-both-eyes-open target acquisition. It is specific for the Sage single and multiple projectile 37 mm rifled launchers for less lethal applications. Because it's powered by a single transverse-mounted CR123A battery, the XPS2-Sage is shorter than the N and AA battery versions - yet it delivers the same parallax-free sighting capabilities. This sight requires a mere 2.75" of rail space. The battery cap is a simple screw-type cover that's o-ring sealed and tethered to the housing. The control buttons are positioned on the side of the rugged aluminum housing for ease of operation. The illuminated reticle is calibrated to the specific trajectories of the Sage less lethal applications - the illumination system provides the operator with 20 brightness levels to choose from. The reticle combines a targeting and ranging reticle in one image. Designed for today's modern battlefield; the XPS2-Sage is submersible to a depth of 10', and it's repeatable to 2 MOA after remounting. The rear window is a 3/16" thick shatterproof laminate with anti-glare and scratch resistant coatings, and the front lens is 1/8" solid glass. Because the optical system is based upon transmission holography, parallax error is not an issue - a mission-critical feature that can save the situation when the going gets hot.
