This package includes the EOTech EXPS3-4 Holographic Weapon Sight, the G33 magnifier and Switch to Side magnifier mount with quick detach. The EOTech EXPS3-4 has all the great features that EOTech Holographic Weapon Sights are known for in a significantly more compact package. This optic features a 7mm raised base for better iron sight access, and an adjustable quick-detach lever for easy and repeatable attachment and removal. The more compact design only requires 2.75 of rail space! The compact design used by the XPS and EXPS models was created by separating the battery compartment from the base and mounting it transversely. This not only dramatically decreases the over-all size of the optic, but allows the battery compartment to easily clear the delta ring on M4/M16 platform carbines and rifles. The AR223 4-Dot reticle features a 65MOA circle for fast target acquisition in CQB scenarios with (4) 1MOA aiming dots. The XPS3 and EXPS3 series are night vision compatible. The EOTECH G33 Gen III Magnifier w/ STS Mount, Black (G33STS) is shorter and lighter than the G23. It offers a new and improved mount providing faster transitioning from 3x to 1x, tool free azimuth adjustment, larger field of view and an adjustable diopter for improved, precise focusing.
