Wont this give you unlimited ammo?
001001001001001 gives you 5 AK mags..
Maybe making them drop the weapon, and move it to an ammo crate or underground/in sky?

[Edit : Just though : removing the weapon doesn't remove the mag? If so, remove the addmagazine bit, you'll only be able to carry the nomal ammount of mags, say, 8, but spread between the two weapons, so 4 each)]
