Hokay, just to clear some things up - yes, the vz-58 is still in service with the Czech Army, and is being phased out for the CZ 805 select fire rifle.

Yes, Czechpoint is importing vz-58s, but they are made with a Czech receiver, made by Czech Small Arms, formerly known as D-Technik, in the Czech republic. They come in with a magwell for single stack mags, and are CNC'd to accept the standard 30 round mag here in the US, outfitted with compliance parts.
Yes, 30 round mags are available from Czechpoint, for as low as $15 a pop.

CZ-USA was selling the Czechpoint rifles, a business arrangement that ended some time ago. CZ-UB still offers the real and original vz-58 to international customers...

...but that is the select fire version only, not a semi-auto only clone for US use. I can only hope they will make an 805 clone for US distribution...
The vz-58 took everything about the AK and made it better.
Lighter, more accurate, durable and easy to use. My opinion, based on real world experience with both rifles.
Having said ALL of that, I hope the OP is able to find something that is available and legal in his neck of the woods - one would think FALs and AKs would be everywhere.
