The EXPS2-0 Holographic Sight from EOTech is a holographic red-dot sight that provides rapid heads-up-both-eyes-open target acquisition. Sporting a shortened form factor to save valuable rail-space, the EXPS2-0 has accessible side buttons and a single, quick release throw lever for easy attachment and removal.
Because it's powered by a single transverse-mounted CR123A battery, the EXPS2 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, and the battery compartment is separated from the base to allow it to hover over the Delta Ring of most M16/AR15 platform firearms. 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 configured with a 65 MOA circle and a single 1 MOA dot - the illumination system provides the operator with 20 brightness levels to choose from.
Designed for today's modern battlefield; the EXPS2-0 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 which can be a mission-critical feature.
