Get the Eotech XPS3 Holographic Weapon Sight 1x 68 MOA Ring/1 MOA Red Dot from BattleHawk Armory! The HWS XPS3(TM) is the shortest and lightest night-vision compatible HWS yet. Powered by a single transverse mounted CR123 lithium battery, the XPS provides additional rail space, leaving more room for rear iron sights, magnifiers or night-vision mount. Our most popular reticle offered, the 68 MOA ring with 1 MOA dot provides three usable aiming points. The aiming points above are based on the following load: .223 cal. 62 gr. 2,900 vel. When using other loads and calibers, the opera- tor will have to establish the ranges associated with the aiming points. When using a shotgun, the 68 MOA ring can be used to represent shot patterns but will vary based on choke and shell selection. For ordering this reticle, the model codes will end in -0.
