Q: I live in a New York state where only legal high capacity magazines are those manufactured prior to 1989. When were your vz. 58 magazines (and vz. 61 magazines) manufactured ?
A: All vz. 58 thirty round magazines and all vz. 61 magazines were manufactured prior to 1989.
Take a look at their site (http://www.czechpoint-usa.com) and if you are serious about buying a VZ58 send me a PM and I may be able to hook you up with a really good deal on one...assuming the latest batch hasn't sold out yet.
