That's one cool video of the VZ 58 assault rifle in action. Many guys firing the VZ 58 in semi and full auto at targets. Really well made video, and I love the heavy rock music that is on that video. Check it out!
The Czechoslovakian VZ 58 assault rifle was designed in 1956 and adopted in 1958 by Czechoslovakia's armed forces. Looking very similar to the Soviet AK-47, it is a totally different rifle internally and the magazines can't be interchanged even if they are chambered for the same rounds.
