EZshoot Reflex Sight Red Green Dot Gun Sight 4 Reticles with 45 Degree Rail Mount, Reflex Holographic Rifle Optic Scope, Upgraded On/Off Switch

Not bad for a .22lr MP5. Not the most accurate, but fine for its intended purpose. The instructions didn't cover the brightness settings at all. You press the power button (red or green) repeatedly to select one of the 8 brightness levels. No clue on how many clicks moves the sight adjustment how much, you just turn it a little at a time until it's on target. Changing the reticle seems to change the sight adjustment, so it has to be sighted in on the one you like and just continue to use that. All minor things, though. The features this thing has are pretty nice for the price and the light filtering glass is surprisingly good. The bonus 45° mount was cool, but i haven't used it yet. For the price, you can't really go wrong.

Very bright

Hey, for a cheap red, green dot sight it's great. Haven't had a chance to actually test it under fire , but, on a low recoiling rifle so don't expect any problems.

I was pleasantly surprised to discover that the sight kept it's Zero on my ar-15 after 150 rounds and seems to be going strong!

I bought 1 to try it out and it was so good I bought another one. I use it on a pistol & rifle for rimfire challenges. Quick target acquisition and plenty bright even in the sun on both colors unlike another sight I tried. Holds a zero even when changing reticles unlike another sight I tried . Would buy again if I need more.

When I first received the sight it was easy to install on my pre installed rail. I installed it on a semi auto 12 gauge. With 2 3/4 target rounds it worked flawlessly. It stayed accurate throughout 20 or more rounds. As soon as I used a 3 inch slug, the first rounds recoil blew the lens out of the frame. Such a shame. It worked so perfectly and looked amazing. It’s probably my fault. I did not check the recommendation on the round size. I glued the lens back in but it doesn’t work near as well.

Seems like a great deal, feels solid at first but then When I looked closer the bottom is not sealed and motherboard is showing.. and water or dust inside will fry the chip. Maybe got a bad unit

It was originally great, it came zeroed. However, transporting it attached in a case, the glass fell out.
