The XPS2 is one of the shortest, smallest, and lightest holographic weapon sights offered by EOTech! This compact optic takes up very little rail space, allowing other accessories such as back-up iron sights and magnifiers. The XPS2 utilizes EOTech’s popular One Dot Reticle, which is composed of a 1-MOA dot in the center of a 68-MOA ring, with additional vertical and horizontal stadia. The center dot can be used to accurately engage targets at ranges from 50 to 200 yards, and the lower vertical stadia can be used to make quick close range shots. The One Dot Reticle is optimized for rifles chambered in .223/5.56, but is also compatible with other weapons such as shotguns where the 68-MOA ring can be used to represent shot patterns. In addition, the XPS2 operates on a single CR123 battery and features a runtime of 600 continuous hours (at setting 12).Features of the XPS2 Holographic Weapon Sight: Compact, low-profile designOne Dot Reticle600 hour runtime EOTech XPS2-0 OD Green Holographic Sight w/68 MOA Ring & 1 MOA Dot XPS2-0ODGRN
