EOTECH EXPS3-4 | Holographic Sight | 1x

The EOTECH EXPS3-4 is a compact holographic sight designed for fast, two-eyes-open target acquisition and low-profile mounting on Picatinny rails. It uses side-mounted controls and an adjustable, locking quick-detach lever to allow rapid attachment and removal while preserving lower 1/3 iron-sight access. The EXPS3-4 is night-vision compatible and runs from a single 123/CR123 lithium cell, making it suitable for day or night field use.

Common applications include close-quarters target acquisition and tactical training or field shooting where rapid sight picture and durable, repeatable mounting are required.
