M4 Carbine with Red Dot if you want to win. If it's a free for all match, then I put Bandolier, Sleight Of Hand, Deep Impact. If it's a S&D game, then I would swich the perks around to Bomb Squad, UAV Jammer, and Dead Silence. The MP5 is awsome silenced or not [depends on the game you are playing], but I dont use it as much anymore because I always die while reloading. AK74u is also good. Mostly I use the R700 and the M40A3 with Bandolier, Sleight Of Hand, Deep Deep Impact[in free for all games].
