L96AW best sniper tho its pain in the ass to master the whole sniping at black ops.
Galil and Ak47 are best by far at assault rifles well famas is quite good to.
And last everyone who uses submachine guns(expecially whit rapidfire+steady aim) are total nubz who dont know how to aim. So LearnToPlay w/o random hipfire shit. U may own at publics whit ur submachine guns but go play some real games at clanbase ect and u will learn that u suck w/o perks+attachments.
