The build is very powerful, the infinite ammo allows you to move quickly taking down a lot of cops it can easily take down enemies with headshots and bulldozers arent an issue the build can be augmented depending on what you want. you have about 10 skill points of flexibility, you can use the oversaw if you want i am using it because the izhma is more than enough firepower to take on missions. always aim for the headd and you will have no problem at all.

The Izmha is the main weapon of this build once fully buffed it packs quite the punch
The weapons specifications are as follows

Ammunition: 000Buckshot
Barrel EXT: SHH!
Foregrip: Tactical russian rail
Gadget: LED Combo
Grip: AK wood grip
Stock: Wide stock/2 piece stock

its fairly simple and extremely fun
the build can also use the steakout 12 gauge as it is better but since i dont own that dlc i uesd the izhma.
