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!"

Pretty clear not much tint as other people say, using it for airsoft not a real rifle. Easy to install just make sure to have lr44 battery’s on hand came with only 2 need 4.. functions pretty good for airsoft.

I'm usually not a big fan of 1X optics but this one is both cheap and decent. It doesn't weight a whole lot and the sight picture is amazing. My only concern is the red option isn't super visible outdoors but green is perfect in all settings. Overall, for the price this is great.

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.

Upon receiving the sight it does not work out of the box I think batteries are dead but it doesn't work

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

Great product for the price

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