The Czech rifle uses a short stroke piston and a locking block locking system compared to the long stroke and rotating bolt of the AK family of rifles. The propriety VZ58 magazine has a provision to permit the bolt to lock open on the VZ58. The VZ58 has found its way into conflicts throughout the world such as the Vietnam War.
The Czech Point VZ58 here is a commercial rifle manufactured in the Czech Republic. It is extremely well made and completely reliable. The only issues I had were due to my large frame, big hands and long arms. For me, the stock was way too short and pistol grip too small. For a normal sized person, this more than likely would not be a problem. This is a great rifle to have in a collection. Still in use by the Slovakian Army, once they completely replace the VZ58, there is a better than average chance production will cease for good.
