What Ian said.
If you're going to do this, it's got to be done right with CS or equivalent, which no one has access to. Well, no one that would want to do this, anyway.
Other than that, why? Airsoft is supposed to be fun, not a recreation of everything that sucks about Army training. :lol:
Honestly though, I'm always down to try new stuff. I just happen to have a couple masks that I've collected over the years.
