While the appearance of the VZ 58 looks similar to the AK-47, it was inspired by the German StG 44 and initial development was actually based on the 7.92 x 33. Mechanically, the VZ 58 is completely different from the AK-47, and no parts including magazines are interchangeable.
Differences between the VZ 58 Sporter and the AK-47:
" The VZ 58 has a milled receiver, the AK-47 is stamped.
" Even with the milled receiver it is almost one pound lighter than a stamped AK-47.
" The bolt of the VZ 58 stays open after the last round in the magazine has been fired.
" The VZ 58 has a more natural point of aim and is faster handling.
" The safety is more ergonomic making a faster first shot possible with the VZ 58.
" The ejection port is HUGE. There is no chance of an empty case getting stuck in the action of the VZ 58.
" The VZ 58 gas piston can be removed or exchanged without tools.
" The alloy magazine of the VZ 58 is half the weight of the steel AK-47 magazine. (.42 lb. vs. .84 lb.)
" VZ 58 is easier to field strip.
" The VZ 58 is striker fired unlike the hammer fired AK-47. This reduces the number of parts and possible points of failure.
