Any fun build recommendations? (Payday 2)

Just got to Infamy I (almost Infamy II). I’m currently running a rogue dodge build with a CAR-4 rifle and the typewriter thompson but I’ve grown a bit frustrated with the CAR-4.

I want a dodge build where I can just mag dump entire hordes of policemen without any worry about ammo capacity. Yall got any fun builds I can try out?

(Honestly just a replacement AR for the CAR-4 will do, I have like one and a quarter magazines worth of ammo in that thing.)
