551 Metal Holographic Bright Green & Red Dot Sight

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.

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.

Works great, bright in outdoor setting. Easy to switch colors and change brightness. Clear visibility

Works well for my AR and easy to sight in.

Glass too dark for indoors, taped together batteries and unclear instructions. Finally got to range and this was extremely hard to zero ( backwards adjustments) and definitely doesn’t hold zero. A refund would be appropriate.

I like that it was able to hold zero on my 9mm pcc after about 100 rounds brite sharp sight picture, it's made pretty sturdy not that I'm going to beat it up but for the money it workIt does what I need it to do.

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

For the price…. it works, looks good, hold very sturdy on my rail. Tint is not as dark and blinding as people claim and also the reticule is not taking up the entire view and painting over the targets. The reticule image is sharp bright with both colors, very impressive to be honest. Held Zero with x2 45mags of 556 at 30 to 50 yrd…remember it’s a replica of the EOTech(which a real EOTech can cost you 400 to 1200)…..so you get what you pay for …I guess people didn’t do the research and cost price of the real one before buying and reviewing this one..but if you want good quality with shocking amazing results for $40 to $50 bucks you can’t bet that(again 400 to 1200 vs 50)….. I would give this model and company another try if they made a updated or newer version…I can say I used both EOtechs and ACOGs on my deployment weapons and was deployed x4….and this replica feels just the same….again feels the same
