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. The XPS2-1 new size allows more rail space for rear sights or magnification.

• 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: 1-single 1MOA aiming dot
• The XPS2 is not Night Vision compatible, for Night Vision compatibility see the XPS3 sights.
