EOTech Holographic Sight XPS2

Shortest model sight yet! This sight is smaller than the former N-cell battery sight (511/551) and runs on a single 123 battery. It also has a longer battery life than the N-cell style sights. With the new single battery configuration, the XPS allows more rail space than ever, leaving more room for rear iron sights or magnification.  Smaller, lighter and always fast; the XPS series is a great new additon.
Single transverse 123 battery to reduce sight length
Shortened base only requires at most 2 3/4i nch of rail space compared to the 4 inch N battery sights
Battery cap and latch are eliminated and replaced with a simple O-ring, tethered cap; better sealing is achieved
Battery compartment is now separated from the base to allow it to hover over the delta ring of the rifle
Average battery life at brightness level 12 is roughly 600 hours, 3X battery life of N cell sights
Reticle: 68 MOA Ring with 1 MOA Dot
The XPS2 is not Night Vision compatible, for Night Vision compatibility see the XPS3 sights.
