I like Sor-556 MK2 / KORD 6P67 / NVO-228E And L85A3 but only cause i used it on other games , using AR's on anything apart from assault is pointless though the guns all handle differently on each class its so stupid how they've built the class system to be more " balanced "
Carbines / are the way to go though if u like using the full auto machine guns
cause SMG has weird nerfs same as assault guns on other classes u just wont hit what u aim at most of the time, all the guns are inconsistent with how u think theyll act in this game
