Stamped design? I think you're thinking of MAK-90s or AKMs. AK-47s (up through the 2a, at least) have milled receivers and machined piston guides. And the receiver cover is stamped, but that's sort of an insignificant to the operation of the firearm.

We're I equipping a small army, I would look into something like the galil which mixes the best features of the AK (easy to manufacture lower receiver and reliability) with the best features of US weapon systems (accuracy at 300-500m). And the bottle opener on the front handguard is a definite plus.
