( I think the ammo bag should only be able to give extra Bullet magazines. )
With the new kit design system that is being developed by the devs where instead of kitbags you see the actuial gun and or missle tube.
My suggestion is as follows
instead of having an ammo bag have the players holding a magazine clip or 2 in their hand. they throw the magazine(s) to the ground and the other players can pick them up.
an ammo bag would still work in this case but i think this would be a little more realistic.
EX:


OR if this is an accepted idea. Remodel the ammo bag to an ammo box.
