KF LAW flashing red-dot sight

[Tefaan]

Hello,
I wondered about the red-dot sight of the LAW since I found out there sometimes is a red bigger circle around the dot. It's flashing on the position where I took the screenshot but only there I discovered it. Take a look at this picture:

Do you have a clue what this could mean? Or is it just a bug? I think it happens sometimes on other maps too but I'm not sure.

What's the difference between those sites and why should I use it?

Because imagebannana sucks and i dont want some big *** advertisement in my face when i only came to look at a single picture for like 5 seconds.

Sorry, I didn't know about the advertisement since my browser blocks ads. But back to topic. Does anybody have a clue about that?

Seems like surface is wrongly reflecting emitter. Same sometimes happens with M14's laser dot.
