The EXPS3 sits at a lower 1/3 co-witness height. Back up ironsights can be seen inside the window, but in the lower 1/3 of the optic. Buttons on the left side allow you to toggle through the 20 daylight brightness settings, and the NV button switches to a dim mode for use with night vision. The optic can be seen in NV mode by either running a PVS-14 mounted to the rail behind the Eotech, or by getting a cheekweld while running bino NODs.
Runs on a single CR123A
The Airborne Charging Handle is 3D machined from a solid block of aircraft grade 7075-T6 aluminum. Its ambidextrous design allows for seamless operation from either side of the weapon. The levers are dual contoured similar to that of the charging handle of an M14, where not only the x-axis but also the y-axis receive radius cuts. The handling surface of the lever is also checkered, adding a textured grip aiding to the use when operating with gloves.
