Many gun owners seem to set their eyes on EOTech’s lightest and advanced holographic weapon sight today. As this scope dazzled in the spotlight, our team decided to do an EOTech EXPS3 review to dig further and unveil the reason why it made the firearms community wild.

The EOTech EXPS3 is an operator-grade HWS built for close-quarter engagements with fast-moving targets. It has one-MOA dot and a 65 MOA circle for faster target placement. It delivers two-eyes open shooting and a 7mm raised base for lower iron sight access.

The EXPS 3 also features a quick-release lever for easy installation and removal. It has an aluminum shrouded side button for easier control access of its windage and elevation.

EXPS3 reflex sights come with an auto-shutdown feature and use a CR123 battery in a transverse orientation. Its battery compartment is sealed with an O-ring, making it waterproof and fog proof. It also features an NV capability that works with Gen 1-3 night vision devices.
