The EOTECH EXPS3 Holographic Weapon Sight is a lightweight, non-magnifying, optical sight designed for close to mid-range engagements. It provides very fast target acquisition and engagement at short ranges while providing aiming capability out to 300 meters equal to or better than iron sights. The EXPS3 features easy-to-adjust side buttons, a quick-detach lever, and a transversely-mounted lithium CR123A battery. The increased height of the EXPS creates a lower 1/3 cowitness with iron sights.

This 68 MOA ring provides four usable aiming points; 20 and 200 yards at the center dot, followed by 400, 500, and 600 yard 1 MOA dots. Use 62 gr .223 Rem FMJ with this ballistic reticle at roughly 2,680 fps with a 14.5” barrel. Aiming dots my not be distinguishable without magnification.

EOTech EXPS3-4 w/G33


Great system!Lowest price by far, and I did extensive research.Very knowledgeable personnel.Will shop there again.

Excellent combat sighting system.


Some have questioned the relevance of this system given all the variable powered scopes out there. The anwer is the holographic targeting system. It is very fast and accurate. This system is good to 600 yds all day. If you don't need the magnifier, you can remove it lightening the set up. Rugged. Easy to adjust.

Overall very satisfied.

I like the functionality of this optic and the magnifier makes a world of a difference. the QD design is very thought out but be aware that this unit is rather heavy since its a combo, I do not run any BUIS with this setup nor any other attachments. However the performance, adjustability of the red dot along with the NV capability makes it well worth the premium.

If you don't have perfect vision be wary....

If you don't have perfect vision be wary. I can't ding this optic too much because my vision is not all that great. That being said, my heart sank when I took my EXP3-4 out of the box and looked through it. The red sight ring and dots were super blurry and looked extremely pixelated. To my eyes it looks like a jumbled pile of individual pixilated red dots. I am used to running multiple different Aimpoint red dots with Larue mounts and this EOTech sits noticeably lower and I have to have my face buried into the charging handle to get a good sight picture. The blurry red ring completely covers targets up, up close. When looking through the magnifier, the red ring and dots are much much cleaner and I only wish it looked this way without magnification. I will be returning this for a Primary Arms illuminated 1-8 Raptor. My crummy vision make this EOTech an unfortunate no go.
