I bought this on TacSwap. Everything looks good, and quality, except something just looks a bit off about the plastic around the glass. It looks cheap, and a bit shiny. Am I overthinking this?

If the reticle looks like it’s made up of a bunch of tiny dots it’s real.

Good deal. Is there a reason that's the case?

Variations in polymer batches is common.

I had a 512 like that. My 552 is more dull/satin sheen.

Because it’s not a Chinese LED

Yup. There’s like 4 companies that make a holographic sight, the cheap Chinese ripoff shops ain’t gonna do it. I have a knockoff EXPS 3-0 out for review and it’s very obviously an LED.

If the lenses are not shiny, and the reticle is not an LED, you should be fine.

We have a lot of used Eotech's come through our shop. There's even a lot a variability in the reticle clarity. Some are fairly crisp, while some are pretty fuzzy.

Because a holographic reticle is an interference pattern of light recorded onto a holographic plate, when coherent laser light illuminates that plate, it diffracts the light to reconstruct the original wavefront pattern, producing the holographic reticle. A fake would be using a simple LED projection onto glass like any typical red dot, which wouldn't have the same appearance.

Thank you.

And thank everyone else who responded, you've put my mind at ease.
