The only thing I would ever use these in, is a claymore mine.
Oh goodness no. Those are more for amusement purposes; I don't even know if "game face" meant to sell them for real, or just did it to mess with people.
(I would love to see a test where they run 1000 rounds of G&G Bio's through an AEG, then 1000 rounds of "marking" BB's and compare negative effects)
