551 Metal Holographic Bright Green & Red Dot Sight

5/5 stars"I'm blown away by the Ohhlion holographic sight! It holds zero perfectly, even after repeated use and rough handling. The fitment is excellent, and the viewing window is crystal clear. I love how it performs in both bright outdoor conditions and low-light indoor settings - the brightness settings are spot on. The sight is incredibly reliable and accurate. One thing to note: to turn it off, you'll need to either press both arrow buttons simultaneously or hold the NV button - a bit unconventional, but easy to get used to. Also, keep in mind that it takes AA batteries, which aren't included, so be sure to pick some up. And the best part? This unit is a fraction of the price compared to the brand name units, offering incredible value for the performance you get. Highly recommend this optic to anyone looking for a top-notch holographic sight for hunting, tactical, or competitive shooting without breaking the bank. Great job, Ohhlion!"

Great producted and easy to use!

Works pretty good for the price haven’t put a ton of rounds through it yet interested to see how it holds up, can be a little difficult to see in direct sunlight but not terrible using green. Looks like a pretty decent unit, only “complaint” I would have about it is the elevation and windage adjustments they seem to be the weak point in this sight and make it kinda hard to dial in right. Easiest if you use a vice or lead sled. Overall fairly satisfied

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.

Showed up with only 1 battery instead of the needed two couldn't find the battery's anywhere too

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

I use it on my real steel AR and my airsoft gun. It works on both.

Very impressed by the quality, especially for the price point!
