Why EOTech

EOTECH brought the holographic sight to market in 1995 out of Michigan. Instead of reflecting an LED dot, it lights a reticle recorded on holographic film with a laser. L3 owned it until 2020, when American Holoptics bought it.

The EXPS3 is the sight you see everywhere. It's 3.8 inches long, weighs 11.2 ounces, runs one CR123 for about 1,000 hours at setting 12, and has 20 daylight and 10 night vision settings. A 68 MOA ring around a 1 MOA dot makes it fast up close.

The XPS3 is the shorter version on the same battery, and the 518 runs on AA batteries. The G33 is a 3x flip magnifier at 7.8 ounces. The EFLX is a pistol dot, and the company now sells scopes, lasers and DCBL titanium suppressors too.

EOTECH is the most added optic, in 40% of builds that have one, and its G series is the most added magnifier at 43%. You pay for it: about $1,290 against roughly $485 for the typical optic, and $575 against $300 for a magnifier.

Battery life and weight are the trade-off. About 1,000 hours on a CR123 means you change batteries on a schedule, and 11.2 ounces is heavy for a 1x sight. The 2015 thermal drift lawsuit against the old owner, settled for $25.6 million, still comes up in every forum argument.

For 2026 the EXPS3 HD drops the hood for an all aluminum body and adds a side dial with night vision positions, auto brightness and shake awake. EOTECH also bought VK Integrated Systems in 2025. Most of its listings were in stock in early October.

We'd buy the EXPS3 if you want the classic fast carbine sight and don't mind paying for it. Start with the sight alone and add a G33 later.
