OTW Red Dot Sight,1x20mm/ 1x27mm 4 MOA Red Green Dot Sight Micro Rifle Scope

I have been looking for quality affordable optics for my .223 Wylde AR. I watched lots of YouTube videos and even more reviews. This is the sight I decided upon. My decision was primarily based off of one particular video. It shows this sight being beaten against a drum, immersed in water, and pounded with a water bottle. It still held zero after that. So, I have high expectations for this sight. It comes with batteries and Allen wrench. The picture on the box shows a 1" Weaver riser on it, however, one is not included. Depending on where I place my irons, I may or may not need a riser. If you need one, check out EBay. Much less expensive there. Amazon was the best price for this sight, however.The fit and finish on this sight are excellent and it has your chkice of red or green dots in the viewing window, each with 5 levels of brightness. It is also rated for immersion and impact resilience. So far so good. I highly recommend this sight. It's also priced VERY nicely.

I'll update the review as time goes on, but so far so good on this optic! The turrets are crisp and tactile. The dots at the brightest level seem super bright. I haven't tested it outdoors in the afternoon sun yet but I will. The camera balances out the dots so they seem dim in the pictures but they're REALLY bright in person so I don't think afternoon sun will be a big deal. Again, I'll update as I go.The turret caps are nice, except I wish they had little ridges in them like my Sig Romeo 5 so you can use the turrets as tools to adjust the turrets easier. Otherwise you'll need a coin or something similar to turn them easily. They're not exactly low profile but I don't find them extremely obtrusive or anything either.The dial to adjust brightness is nice and stiff so you shouldn't have any reasonable problems with it getting turned accidentally.The mount seems fine. Again, time will tell if it comes loose under fire.Just inside of the glass you can see a ring of plastic which I believe houses the electronics. It's not super noticeable unless you are really looking for it.Overall a good budget optic that I think will hold up well. There are torture test videos out there that show it's pretty sturdy.

Solid optic. I wanted to try another style optic with a green dot as opposed to my Delta Point Pro without spending $500 . I found this and so farso good. Stout housing and removable picitinny mount in machined aluminum. Elevation and windage knobs can be adjusted with a small screwdriver or your fingernail. That is preferable to looking for a tiny hex key. The adjustment knobs have O ring gaskets for the covers. That's another good thing. If you like red dots, there are five brightness intensities to select from. If you don't like red, you have a dot in green with 5 brightness intensities. You don't have to sight in both dots separately, once you have one color on point, the other color is sighted as well. Low profile optic that will co witness with taller irons. Comes with rubber lens covers. It has taken some abuse so far. I haven't mounted it on anything that kicks harder than a .223, but it survived a drop of about 6 feet to concrete and held zero. I am happy with it.

UPDATE – 1/9/19I changed my 1-star to 5-star review because the problem describe in my initial review isn’t with the sight, but rather the user instructions supplied with it. Also the company’s excellent customer service rated an upgrade - I was supplied with a new unit even though the warranty had expired. My original review was based on me trying to insert the CR2032 battery called for in the instructions. The unit actually takes the smaller CR1632 battery – that is what caused the problem. I removed the old battery and disposed of it when I needed a new battery and a couple of weeks later I checked the manual for what I needed to purchase to replace it. The ORIGINAL POST and UPDATE are below. One IMPORTANT note: the company still has the wrong battery size in the instructions. I have been very satisfied with this red dot’s performance on my AR-15; it holds zero and has a clear image with the perfect size red dot for me. This is an entry level sight, but for the money it can't be beat. If you want to try a red dot and don't want to spend big bucks without knowing if it is a type of sight for you, this is an excellent choice.ORIGINAL POSTI just tried to change the battery in this sight for the first time and I could NOT get the new battery in! All of my other red dots have a ridge/lip that holds the battery in place when you screw the cap on the battery compartment. This unit does not have one and it is impossible to get the battery to stay centered as you try to screw the cap on under pressure with the fine threads that it has. I tried to contact the seller at the email address they posted to respond to in another person's post and my email server says it isn't a valid email address. I would WARN anyone that considers this unit that after the first battery dies, you will NOT be able to replace it and the seller poster a false email address to respond to. The sad thing is that I loved this sight on my AR and had intended to use it regularly. Be forewarned!UPDATE 1/4/19The email address mentioned above was actually good if I inserted the missing "@" where it was omitted by the SELLER. I just copied and pasted it without paying attention to the SELLER's error. I corrected the address and I DID get a response that said they would supply me with a new unit after I supplied them with my order number. They even extended the warranty to cover my sight. I look forward to the new sight because I would like to put it back on my AR. I might be dealing with them directly in China for all I know and the exchange might take some time, but I guess time will tell.
