I personally run a full paintball mask...but it's the DYE I4 and I haven't shot a rifle where scoping is a problem with it.
Partly this is due to the fact that I don't have the $ to buy a good set of goggles now that I'm legal
and partly the mask never fogs, and doesn't use one of those noisy fans.
