I am personally in love with my KJW M4, I've been able to game it once in a skirmish day, otherwise I wouldn't match up with those damn high capacity mags on AEGs, so far with 4 mags x 38Rnds in single shooting, I can manage to have enought ammo for a while. In milsim type games where there's no trigger happy, it's so fun to have, but bye bye the silent shooting, everyone on the field can tell where you are. But I kind of like that
