And then there's the fact that the Kalashnikovs everyone uses keep switching between being submachine guns, rifles and machine guns.
I'd assume most of the AK74's would break down over time, so their price goes up and they become more scarce. So people would be stuck making the Bastard Guns, shotguns, and anything that uses combustion. Also ammo for those dshkm's mounted on the tripods would be scarce.
