You joking or you serious? I personally hate how every AR in the game can kill you in three zero-recoil bullets, giving them versatility in literally every range outside of melee. The system is broken. Because most people fire Akimbo 1887s at the same time, there's more than enough time to kill the person if they miss and you're on your game. I don't like the way the game works, but if they're going to make it so easy to kill someone ANYWAY, then the Akimbo model 1887s are balanced well enough.
I'm surprised more people don't complain about getting one burst killed from the FAMAS/M16 at short, medium, and long range. ARs in this game basically make every other weapon type useless. They have excellent bullet penetration esp. with FMJ. They do just as well as SMGs in close quarters and equally as well as snipers in long quarters. There's no balance. ARs rule this game.
