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. Smaller,lighter and always fast with three reticle options. With the new single battery configuration, the XPS allows more rail space than ever, leaving more room for rear iron sights or NV mount.

Single transverse 123 battery to reduce sight length
Shortened base only requires at most 2 3/4 inch 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 500-600 hours, 3X battery life of N cell sights
Three reticle options: 0- 65MOA circle with 1 MOA aiming dot, 1-single 1MOA aiming dot, 2-65MOA circle with two 1MOA aiming dots
Available in Night Vision (XPS3) and non- Night Vision (XPS2) versions. The numbers reflect the number of the buttons on the back of the sight.
