EOTech EXPS3-4 Holographic Weapon Sight
The EOTech EXPS3-4 has been developed to optimize the functionality of the holographic weapon sight (HWS). The buttons have been moved from the back to the left side for instant access, allowing a magnifier, night vision or a back up iron sight to fit closely to the HWS body. This new button position allows the user to operate the HWS function switches easier than ever before. The EXPS3-4 is configured with a new ballistic matching reticle image for the M4 carbine. The battle tested circle dot reticle will be offered along with a series of 1 MOA aiming dots that are vertically aligned and calibrated specifically for the ballistic drop of .223 caliber ammunition.
Because it's powered by a single transverse-mounted CR123A battery, the EXPS3-4 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 fit 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. This allows a magnifier, night vision device, or a back up iron sight to fit closely to the HWS body. The illuminated reticle is configured with a 65 MOA circle and four 1 MOA aiming dots. The series of 1 MOA aiming dots are vertically aligned and calibrated specifically for the ballistic drop of .223 caliber ammunition. The reticle provides 4 aiming dots for target distances of 0-300m, 400m, 500m, and 600m. The use of a magnifier is strongly recommended.
Designed for today's modern battlefield; the EXPS3-4 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.
