EOTech EXPS3-2TAN Holographic Weapon Sight
the L-3 EOTech EXPS3-2 holographic red-dot sight provides rapid heads-up-both-eyes-open target acquisition. Sporting a shortened form factor like the original XPS3, The EXPS3-2 also boasts a repeatable quick release throw-lever mount.
Because it's powered by a single transverse-mounted CR123A battery, the EXPS3 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 raised to accommodate the Delta Ring of most M16/AR15 platform firearms. The base is configured with a 7.0mm rise to accommodate hand guards and instant access to BUIS. The battery cap is a simple screw-type cover that's o-ring sealed and tethered to the housing.
The control buttons have been placed on the left side of the rugged aluminum housing for ease of operation with a rear-mounted night vision device. The illuminated reticle is configured with a 65 MOA circle and a pair of 1 MOA dots - the illumination system provides the operator with 30 brightness levels to choose from, 10 of which are compatible with night vision gear.
Designed for today's high-tech battlefield; the EXPS3-2 is submersible to a depth of 33', and the QR throw-lever mount is 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
