Typhoon, it rips through AA like knife through butter
Remember, Headshots Only

There is, however, a bug
Shotgun attachment for typhoon works if you use foregrip

Only downside is your pride, it is a noob-style weapon, which is why everyone who loses to it complains
recently i played in a game where there were many scar laser AA users, wrecked them with typhoon, no auto armor, no attachments
