I thought the same thing until I swapped my snapshot/moving target bite of the fox for one with snapshot/opening shot. I get some very suspect headshots with opening shot. Is it worth the trade off for snapshot though? I guess I'll have to put in more playtime.
It's worth the trade off on a rapid fire for sure. They already have high handling. Pair it with sniper or precision targeting and a sprint grip and it will come close to snapshot anyway.
