What weapons have glint?

I wouldn't call it glint though.  It's like a spot light.  They can't seem to get the glint part down like it should be.

My understanding at the moment that it is only sniper rifles that have any glint at all, not even DMRs with high-magnification scopes

You know this is simply answered all you have to do is Google it....

Iron sights is the only sniper sight that doesnt have glint, I have read too that even the anti glint stuff doesnt get rid of it....
