well everybody uses the ak 74u with rapid fire and a grip. Its a noob weopen. However the best class ever is the Galil with a surpressor and my personal best is extended mags. Or u can use any attachment with the galil and still own people. use ghost as your first perk. warlord or slieght of hand as yor second. and ninja as your third. Also sabatage is the best game if u want to keep a good k/d and u can get resonable xp too. I prestige in about on average in about 12-17 hours just depends on if you complete as many challenges as you can. trust me it works. In search use silencer with slieght of hand. also hacker is good to. but sabo is the greatest game mode.

can't go wrong with the FAMAS 74u really.. use the 74u with grip lightweight sleight of hand and ninja.. it's pretty good for search otherwise use the MP5k if you're a low level it's pretty decent to
