Grip
Advance Rifle.
Or
Infantry
STV40
Grip
High Caliber
Secondary who the F^&K cares I die too worry about it. (Side note) use to play where I would do a shot a vodka if my life would last long enough where I HAD to use the secondary. Then I would get drunk and just shoot the walls so I could do more shots… It a vicious circle I tell you
