ESSLNB 2MOA Red Dot Sight, Reflex Sight, Red Dot Scope with Shake Awake and 12 Brightness Adjustment for 20mm/22mm Weaver/Picatinny Rail Mount

I received a sight with a blurry dot. Internal issue. I emailed company, and they sent me a replacement. I got to play with it a little this afternoon. Almost on target out of box. I love that I don't need to carry a little screwdriver in the field. Very nice product for a modest price. If you're sitting on the fence, just go for it!! This company took care of me. Five stars for customer service. 20 dollar sights have come a long way.

Bought this cheaper dot for a air pistol but its to big. The smaller you go the bigger the price. I don't get it. I wouldn't recommend for any pistol. OK quality.

What a hell of a scope. For the money it beats more expensive ones hands down. I’m buying another 3 color scope for a rifle I have. When they get them back in stock. I mounted this first one on a pistol. Even with the recoil it holds zero . (357). If it holds up to that recoil it’s winner. So far so good, waiting for a tri colour to be in the amazon wish book. Hey, shoot safe and it’s our right to own them. Tank Gunner

Bought this for one of my airsoft replicas and works just fine for the price. I don't need a high-end pricey red dot for airsoft so it works perfect for my needs.

I bought this particular red-dot sight because it was listed to fit 3/8 dovetail. The mounting brackets can be flipped upside down in order to fit either Pica-tinny or 3/8" dovetail. Well evidently this company does not know the dimension of 3/8" dovetail. On every pellet gun I owned, I tried to mount this and it would not tighten up. The sight would just slide loosely right off the rail. It appears to fit Pica-tinny OK so if you are buying for that rail system you will likely have no problem. The visual appearance of the dot is typical of any other red-dot in this price range. My 72 year old eyes are limited by occasional dry-eye conditions and by astigmatism and vari-focal glasses so seeing a small precise dot is likely more difficult in my case. The elevation and windage adjustment knobs have a nice firm click to them and the on/off brightness knob also works well. The sight comes with flip-up covers, but the cover assemblies are not tightly fitted or glued to the sight ends so you have to hold onto the base of each cover while popping them open. It is actually easier to just pull off the whole cover assembly at each end since the covers themselves fit snug in the base when closing. Choices are slim for a red-dot sight that fits 3/8 dovetail and considering that the price of this sight is quite reasonable, I've decided to keep the unit and will apply some contact adhesive to fit the cover assemblies securely onto the sight and also do a little metal work (milling machine) to make it work for me. Once I've done this, the option to return the item is, of course, gone so if you feel the challenge to tweak this mounting system, this sight could be a choice for you. A person with some patience and a good file could make this work. Just make sure it functions properly before making the modifications since the warranty will be voided and returning the unit after mods is shady behavior. Unless you have the tools to modify, I suggest avoiding this unit for 3/8" dovetail.Update: I was able to modify it to fit tightly. Each side bracket and the base of the sight needed milling so I likely had to sacrifice the Pica-tinny mounting option in the alteration process which was no loss in my case. I have it mounted on a Crosman 2240 with the metal breach kit and longer barrel. If the manufacturer of this sight would be more precise in the process of making the dual-mount rail clamp, they would have a winner here, particularly given the price of the unit. I really can't make any comparisons to the quality of this sight, since I haven't looked through a red dot sight from one of the more well-known optics companies, but it works well for me in a pellet gun situation. I would consider another one, now knowing I can remedy the misfit to 3/8 dovetail, but I need to knock off a couple stars for the lack of quality control on this issue.

Works always on the money

This scope is of 0 value. Unfortunately, this scope will not hold 0 at all. Currently I have two of them because the first one was defective. Both of them do the exact same thing. After you get it zeroed in, any slight movement and it's gone. Not worth anything at all.

It's plenty accurate on my benjamin np mk2 - holds zero after 100 or so shots to 15 yards(basement range)My only issue is the 1" bullseye is nearly obscured by the flare even at lowest setting on either colorI have other "dot sights that don't have this issueThat said, this is an acceptable sight for the price (so far)Greg
