Most Helpful Positive Review Awesome performance
I purchased this sight in the summer- July or August. The ETA kept getting bumped further... but I was eagerly awaiting its arrival. Then miraculously in October it arrived! I mounted it to my FN509 and headed out to shoot. After a few shots, I moved it 2 clicks to the right and was done. I have sho...

Most Helpful Negative Review Would not recommend
I’ve owned the EFLX for 11 months and use it fairly regularly—roughly 200 rounds per month. Occasionally, it serves as my EDC, but it hasn’t been subjected to any hard use, tactical classes, or drop testing. That said, I’m extremely disappointed in the optic. Pros: • Clean, attractive design •...

Acceptable but not great

by John, Verified Owner from IL, United States Written on December 8, 2025
Is this a functional sight? Yes.

Is this a great sight? No.

Build quality looks good. It is a good looking sight. Performance is meh.

Illumination is a problem with this sight.

This red dot will not perform on a very bright day. Range day in the summer at noon? Barely visible. My PA SLX 3x prism has brighter illumination than this red dot which is extremely confusing considering "red dot bright" is a selling point for an illuminated reticle. Reticle illumination should never be brighter than a red dot, yet somehow the EFLX is dim enough on max brightness (on a fresh battery) to be outdone by reticle illumination.

Max brightness is somehow both too dim to use on a bright day, but also bright enough to bloom out and get illuminator artifacts. Crank the brightness up so that you can see the dot on a marginally bright day and you will be dealing with a halo around your smudged dot.

Battery life is fine. Auto off works but this sight lacks shake-awake(!!!) making it questionably useful on a carry/bedside gun.

This is the first EOtech product I have owned and I cannot help but be disappointed. My friends rave about their holographic sights. I expected this red dot to be of similar quality. I was disappointed.

Vortex and Primary Arms both offer similar or cheaper options for this optic cut. Some of those options also have shake awake tech. I will likely try to offload this sight in favor of one of those options. The lack of features such as shake awake combined with the dim,...

Disappointed

by Jst4Fun, from OH, United States Written on September 29, 2025
I purchased the eotech EFLX less than a year ago at my local Armory. I put it on my Ganik Rival Dark Side. In less than 300 rounds through the pistol the EFLX turned off and will not come on no matter what I do. I even changed the battery thinking maybe nope no go . Very Disappointed at that price point you'd think you'd at least get 500 rounds :-(

Love this red dot

by Torxh, Verified Owner from IA, United States Written on September 2, 2025
The window is large, the glass is clear, top loading battery and easy controls. Plus it’s affordable, not to mention an Eotech.

First optic ever owned

by TommyG, Verified Owner from IL, United States Written on May 14, 2025
This was the first optic I’ve ever owned. I went with EoTec obviously cause of the name brand. I bought this last year mounted it to my Staccato P. Sure you hear stories about this optic. Glass is cheap, it doesn’t hold zero. It’s been on my P since September last year. I love it. Sure I don’t use it a while but I’m getting used to it. I like how you can turn it off and on, make it brighter or dimmer. Good optic for the price point. I’m looking to buy another for the XC next.

It just works

by VAcountryshooter, Verified Owner from VA, United States Written on January 31, 2025
This is the first pistol optic I've ever tried. I mounted it on a Trybe G19 slide. It's nearly a direct fit but more on that later. The dot was nearly perfectly aligned from the box. I had to make a windage adjustment and it was dead on. The brightness settings are great, the battery access is excellent, it weighs next to nothing and doesn't upset the pistol balance, there's no shake or blur. It's really a good optic. Now, the one probablem I have is the included screws don't fit my slide. They were far too fat. The Trybe screws were the right thread pitch but too long and too large head diameter. I had to modify the Trybe screw length and the diameter of the head and it fit up perfectly. If I had an M17 it might have been plug and play, I don't know. I really like it after my whole life of iron sights. It doesn't obscure the target and it was really easy to get used to. Wouldn't recommend trying to carry it inside the waistband.
Pros:
  • bright
  • Sturdy
  • Adjustments
  • Clear
  • ZERO
Cons:
  • Fit
Best Used for:
  • competition
  • owb carry
  • range & target shooting
