Anyone actually using see-through red dot optic lens covers? I'm talking about the ones that come with Aimpoint T2's (and similar) that are see-through. Whats the point if the optic is supposed to be bomb proof? Sacrifical layer? Keep it clean?

Maybe I have too much time on my hands, but I was sitting there looking at it and realized I'm giving up a tiny piece of vision and could not really find a reason why...

Those things are kind of dumb for the exact reason you mentioned.

Yea, I use them as a sacrificial layer of protection. Also, if the optic ends up covered in mud, it’s a lot quicker and easier to flip open the cover than wipe off the debris.

Like grizzman said. Keeps dirt and debris and water off the lenses.
For me optimal is a clear rear lens cover with a solid front cover.
Usable as is, if really dirty you can flip the rear up and still use the optic.

I run a solid black front and clear rear. They help keep rain, mud, etc. out of the FOV. Solid black front keeps me target focused, lower brightness on the dot, and never washes out with a WML.

I have both black ones on my Comp M3 because it came with them. They drive me nuts because I'm always worried about breaking them off, but the temporary rain/dirt protection is nice.

As far as see thru ones. Occluded or unclear dot sights drive me nuts. It's just a personal thing. When I was young I couldn't stand a single fleck of dust on my sunglasses. This is the same reason I hate RMRs with a passion. Like trying to see a the target through a green coke bottle.

Some of the Halosun AEMS red dot's have pretty good glass Lenscovers that flip up. Far better than the Aimpoint clear covers.

That's kind of sad. For Aimpoints ridiculous prices, they shouldn't be getting beat by holo.

Glass for the transparent section is great for clarity and scratch resistance, terrible for impact resistance; I suspect that Aimpoint uses polycarbonate, which has poor optical clarity and scratch resistance, but excellent impact resistance. For my uses, I would much, much rather have the polycarbonate than the glass.

The covers on the 515 series are glass too.
