Phantom: What of the barrel rifling issue? And as to rifled shotguns, I'd ask how they'd be different from a rifle? You're then talking about a rifle with different types of ammo.

And just because the M113 can mount tank guns doesn't mean it's a tank. It doesn't have the armor to be such, and therefore doesn't serve the role of a tank.
