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

Really good budget optic for a handgun. Could use shake awake but the price reflects that it doesn't have that feature. Only used on a range gun.

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

After installation, I went to the range and zeroed it to 36 yards. 40 rounds of 5.56 and it held zero. The adjustments with the tool works good. Avoid purchase.

I got the optic, mounted the optic, and began playing with it. Comes in a super nice plastic case, with foam and some accessories inside, along with its own RMR plates which is freaking sweet. Construction is decent, most is aluminum, and the buttons have smooth-textured rubber over them. There are two adjustments for vertical and horizontal, however adjusting them has very MINIMAL effects on the dot. It will move, it will. Albeit very minute amounts. Not sure how it does real steel, but works great on my WE MP7.

Definitely worth the money for airsoft. Easy to sight in and holds zero.

Not bad for a cheap optic. The brightness adjustment is nice for different environments, although the dot is slightly distorted.

A $20+ red dot doesn't instill much confidence for a combat pistol, but for a .22 plinker it seems to be working well.

Holy hot garbage, this thing is straight junk. Adjustment screws do NOTHING to move the dot, construction is cheap cheap cheap, and the glass cracked after a few mags on an airsoft glock.
