Sightmark reflex EOTech XPS

Sightmark reflex EOTech XPS
When I received my Sightmark reflex sight I couldn't get it to work either. I rushed here to read the reviews and I noticed an awful lot of people having the same issue, I then assumed I just got a DOA like many people did. Then, with patience, I decided to carefully try again: first of all pay attention to that little extra sheet of paper which corrects the instructions on the manual, you have to install the batteries with the + pole DOWNWARDS. Furthermore, to turn the sight ON, you will need to press the button with a quick touch. Just press it and take your finger off quickly. DO NOT keep it pressed otherwise it won't turn on! That being said, the sight is pretty neat, it looks sturdy enough and well built. It looks like it should be able to take a beating without failing easily. The dot/crosshair is crisp and sharp and the 5 brightness settings should be able to cover every light condition. All in all I really like it on my M4, the only drawback is the batteries which are pretty uncommon, expensive and really tiny, which makes fitting 3 of them down a small tube a very tricky experience. I just can't understand why the guys at Sightmark didn't choose a better format. I will have to buy a bunch of batteries on eBay straight from China. Considering the price it is a FANTASTIC item, I am happy I got one.

first of all when I shot it I was out in sunlight in the brightest possible setting, I read some complaining that they could not see the reticle I am assuming they did not know you press the button to change the level of brightness. And as far as the person who says there is a red halo, yes that occurs when indoors and you need to turn the brightness down and no halo. far as zero mine was shooting groups at 50 yards slightly larger than a dime.

I fired 223 and 5.56 rounds out of my windham src with it only about 100 rounds. never once did it turn off on me when I was shooting, it never once flickered while I was shooting. But as I said I have only shot 100 rounds out of it.

also for people who said it did not fit right you do realize there is a bolt on the bottom to adjust its width..... yes when I put mine on first it's all over wobbly and then per directions I adjusted the nut on bottom and it is rock solid on my rifle,

yes I do believe there could be some lemons here and there but I think a lot of the bad reviews are mainly due to user error! It does have a limited lifetime warranty doesn't it?

I will update my review after two more shooting sessions and at least 500 rounds through it but so far I love it and have zero issues.

Buyer BEWARE UPDATED Used ACOGs, EoTechs


Changed to three stars. Couldn't give up on this sight because it has too much potential and it comes from an American company. It occurred to me that "battery bump" might be interpreted by a digital circuit to be a power-off event, i.e. it thinks you turned the sight off. In an analog circuit the sight would just flicker if it momentarily lost power from battery bump. The spring in the battery compartment on my sight was "just" long enough to reach the batteries, but didn't compress. I replaced it with a 1/4 inch spring from my parts bin and solved the problem. The sight doesn't turn off when bumped now. If your sight is turning off or dimming when bumped or on recoil, try replacing the battery spring or stretching it a little bit. You want it to be 1/4 inch long. Haven't shot with the sight yet so don't know about holding zero. Will update again after some range time now that the sight stays on.

Buyer BEWARE UPDATED Used ACOGs, EoTechs
I'm retired military. Used ACOGs, EoTechs, iron sights, everything. Also CEO of an electronics engineering company. (Not firearms related). So I liked the possibilities of this sight but saw a lot of bad reviews. Decided to buy one from a local store in case things went bad. The store had 3, two of which were returns... I got the new one. Seemed to work OK at the store. Once home, noticed sight kept turning off. Started troubleshooting. Found that even a slight tap on the side of the unit would power-off the sight. I believe this is a manufacturing problem since some of the sights work and some don't. Probably related to the "digital" switch circuit. I went to Sightmark's website to see if any of this had been documented. It seems they have closed comments on this sight...but are displaying nothing but good comments...hmmm... If you have a good sight, that's great. But the problems people are having with this sight are real, and I hope Sightmark will fix it.
