FAMAS is an awesome tide-over gun until someone unlocks the AK. Better than the Galil at long range, and I've been ripping people up close as much as when I use the AK. I've been alternating between them lol. Crossbow only has 2 shots, but it's REALLY fun to use, sticking people is fun as shit.
My setups are essentially universal on rifles...All of them run Pro Ghost/Sleight of Hand/Ninja.
