The XPS2 is the shortest, smallest and lightest EOTech model holographic weapon sight available without night vision. It also has a longer battery life than the N-cell style sights. The single battery configuration allows more rail space than ever, leaving more room for rear iron sights or magnification. It has 20 brightness settings and a scrolling feature; locking quick detach lever and a 1 MOA Dot Reticle surrounded by an 68 MOA circle; a 7mm raised base and easily adjustable side buttons. Features Auto Shut Down at 8 hours.
