Gentlemen, Thanks for the input on my question. Think I'll stick with what I have and not waste ammo...
That's using the old noggin! Especially since the work around to get it to work on a VZ58 looks like a royal pain in the ass. If you did get one, might as well fit it to a good AK and get the all-metal Bumpski stock for @ $450.
Although it's pretty cool to have (simulated) full auto capability without going through the NFA and a $30,000 entry fee, the novelty wears off pretty quickly as the spent shells / dollars pile up. And you have to practice to get to where you can actually hit anything at distance. Also, at least on AKs, there's at least the possibility of an out of battery detonation while cycling since safety sears (aka "auto sears" by the BATF) are a big no-no.
