RMR Red Dot Sight, Tactical 20mm Red Dot Sight 3 MOA Pistol Scope Adjustable Brightness with Glock Mount, Reflex Sight Pistol Scope Red Dot Scope Shockproof

Perfect fit and does what it says looks good on my weapon

1. Glass is not glued/INSULATED properly, so when you take a few shots, the glass will either fall out and break on the ground or it will shift during firing and crack in the housing, SO YOU WILL HAVE TO INSULATE IT YOURSELF BEFORE FIRING, WHICH MAY VOID YOUR WARRANTY.2. The reticle is NOT CLOCKED CORRECTLY inside of the housing, so the dot will not go 100% in the directions that isn't clocked.My reticle dot goes from the lower third of the sight window and down WAY WAY below the window. IT VOIDS YOUR WARRANTY IF YOU OPEN IT UP TO CLOCK IT CORRECTLY and I'm sure that the next one WILL NOT BE CLOCKED CORRECTLY EITHER.3. None of the screws actually fit through the optic and screw into any plate that I have enough to feel secure. If you have a drill to add more chamfer to the screw holes so that the head of the screws fits flush or concaved for a better hold on direct mount slides. BUT THAT WILL ALSO VOID YOUR WARRANTY.4. The buttons feel like cheap toys or at least the negative one does. The positive one feels none existent, there is no tactile click at all, just trust that you pressed it...but its functional... IF YOU OPEN IT UP TO SOLDER IN BETTER BUTTONS THEN YOU VOID YOUR WARRANTY.SOOOO YEA, ONLY BUY THIS OPTIC IF YOU HAVE SOME KNOWLEDGE TO HOW RED DOT OPTICS WORK AND ARE WILLING TO VOID THE WARRANTY TO CORRECT ITS FLAWS AND MAKE IT A BETTER PRODUCT WITH YOUR OWN TIME AND TOOLS.

This unit was ok . But it would not fit on my gun . It was a a great price.

I've bought 5 of these so far because I thought it was a pretty good value but the last one didn't work at all? So far no response from the seller, I really didn't think I'd hear back from them anyway?

So this rmr gets a bunch of bad reviews off people trying to use it for real steel guns and for 36 dollars it won't survive on an actual pistol. However for airsoft this is perfect. Tested on gbb pistol and an hpa setup and sight stays zeroed. Dot has 5 settings to adjust brightness and is pretty bright even at the first level. So if you're looking for airsoft this works fine.

I'm going to start with the first problem I encountered with this product which is the fact it took a week longer to get delivered then it was supposed to, I can deal with this ok but the stuff I can't and won't tolerate is the fact that it does not work the adjustment for the wind and direction up an down just turn there is no actual click sounds as described in the description details on sellers page, an does not actually even move the red laser dot that you see when you look through the site. That is a huge let down it's worthless if there is no way to adjust and dial in the point of impact. The point in a site like this is that the dot is supposed to stay on the target at all times no matter where the gun is moved to which it does not it moved with movement of the firearm huge let down and then the fact that the waterproofing rubber seal that is the only way to keep moisture out of the battery compartment is broke do to the fact it's dry rotted completely and wouldn't hold a seal if it had not even broke when I tried to put in a new battery because the one that was inside already did not power on the site at all which is also not cool. Have not been able to get any response from the seller about my situation and it's going to be pointless even if I do because they are going to tell me I need to send it back to them and once they get it then they will send out the replacement that is going to be atleast about 2 weeks before they get it and 2 More for me to get the replacement that is only if they even send it out immediately which I'm pretty sure is not going to be the case and it will be longer time for me to finally get the item back so over about like I'd guests a mate time total from day I paid for the item until I get the one that works is about 2 and half months if not longer and I have a prime membership mind you which my delivery was supposed to be delivered in max 3 days and like I mentioned it was a week and half before I finally got it that's not even counting the weekend only counting actual work days because tothey only go by the week days Monday through Friday that's it. I'd like my money back and a replacement to be honest that is what I think I deserve which not even sure if I would even want to get anything else from this seller to be honest after dealing with the situation I'm dealing with now, I should have just paid 20 or 40 bucks more and got a different one that is what you should do if your looking at getting this

Exactly as described and arrived on time A++

Luckily, I was buying this to build a prop gun for a cosplay. I knew I did not need anything actually function, just something to look the part. That is actually all this is. The glass is horrendous. Anything farther than a foot from your eye and you can't see through it with the red dot on the lowest setting. The dot itself is not helped by this at all. I have perfect vision and this dot is a mess. It is way too bright and the glass being garbage makes it just project all over the visible area inside the sight.If you are looking for something for even Airsoft, look elsewhere.
