OL 551 Metal Holographic Bright Green & Red Dot Sight

Decent product…. I didn’t have to spend hundreds of dollars …

Overall I give the Optic 4 stars for a budget optic but 5 stars for the price range. you can spend a little more and get a Bushnell TRS-25, Sig Sauer or something along those lines however if you're looking for a good Eotech holographic clone on a budget or just for an airsoft gun this is a good choice. For the low price of $45 it's just a good looking sight on your rifle. I haven't tested to see if it holds zero on my AR yet but if you're looking to use it on an airsoft gun it's a solid build. The optic it's self is build pretty well for the price. The only thing I don't like about it is the glass is a little dark and reflective so the view out of it isn't perfect. If it weren't for that I would say this is the best budget optic under $100. For the $50 price range though this is probably the best you're gonna get. I'm genuinely surprised.

Not that I dislike it, it just looks and feels janky. I know it is cheap but it looked really good on the picture. Functional, yet janky. Controls are a little odd.

For the value this is it is excellent. I took it to the range and it isn’t that far off. Obviously it doesn’t perform like an EO tech but for this price it’s pretty nice. My hits were on the mark and I had good sight picture, you really can’t go wrong with this by saving $200 buying this rather than buying an expensive sight that does the same thing

The OL 551 Metal Holographic Bright product is of poor quality. The metal holographic finish is faded and scratched, far from what was promised. Not worth the money.

I mean, it's a 40-50 dollar Eotech knockoff. You're getting what you paid for.Pros -- Decent sized sight picture- Battery seems to be holding up. I've left it on for several days on accident.- fairly easy to sight in.- actually seems durable. Housing feels pretty solid.- Easy controls.Cons -- sight picture, while decently sized, is not particularly clear. It's definitely off colored and a very dark.- It's a large optic for it's class and it eats up a lot of rail space.- The deal breaker; The redical brightness is FAR too low for the outdoors. If you're shooting in low light or let's say - playing airsoft or what have you, it's fine. In doors, it's okay as long as your environment isn't super bright. As soon as you go outside, good luck picking up your redical. On the brightest setting it's barely visible.With this being said, I'd give this thing a 3 to a 3.5. Again, not horrible for the price

seems to be a good optic. i haven't mounted it yet. it looks clear and circle dot is crisp. it is simple and easy to operate. i like it.

Its a cheep knockoff eoteck that works great for airsoft guns. Definitely recommend for that usage.
