A VZ58 can not be converted into a CZ2000 clone. The VZ58 uses a "tipping" action as opposed to the traditional AK operating system. While the weapon/magazines look like a typical AK, its an entirely different weapon and its components are not compatible/interchangible. This is a very high quality rifle, certainly among the best domestic designs in Eastern Europe. Appreciate your VZ58 for what it is, these are awesome weapons and should be appreciated/enjoyed as-is.
I had a chance to shoot a CZ2000 a few years back while I was in Europe working. These are highly accurate and reliable weapons. Certainly equal/superior to a G36K or SiG 552. Fit/finish was exceptional, though I didn't like the folding stock. It felt really sloppy, though this could be because it was a test gun which had thousands of rounds through it in short order. I also like the longer sight radius. Im not sure why you don't see more of these throughout Europe and abroad. I got the feeling they didn't push it very hard, which explains why many AK enthusiasts have never heard of it. IMO, the CZ2000 blows the G36 right out of the water. If there wasn't the bias towards AK style weapons and if CZ pushed as hard as HK, I think you would see many more of these weapons. I don't see this ever being sold in the United States, which is unfortunate as its an amazing weapon which could certainly compete with the emerging gas piston designs. IMO, its right up there with the FNC as the most refined/highly evolved 5.56 AK. While we wont be buying them here any time soon, I would love to see some of the magazines come in. I think these would sell exceptionally well.....
