Shortest model sight yet! This sight is smaller and lighter than the other HWS sights and runs on a single 123 battery. With the new single battery configuration, the XPS allows more rail space than ever, leaving more room for rear iron sights, magnifiers or NV mount.  Smaller, lighter and always fast; the XPS series is a great compact option for your platform.

• Single transverse 123 battery to reduce sight length
• Shortened base only requires at most 2 3/4 inch of rail space
• Battery cap and latch are eliminated and replaced with a simple O-ring, tethered cap; better sealing is achieved
• Average battery life at brightness level 12 is roughly 600 hours
• The XPS3 is Night Vision compatible, for non-Night Vision compatible units see the XPS2 sights.
