Hi. I have a Czech VZ52 semi auto in the rare 7.62x45 calibre. It comes with an adapter for the very common and inexpensive 7.62x39. The gun is in good condition with some dings and imperfections. These were only made for 6 years by the Czechs before the Russians made them change to the Communist standard 7.62x39 of the SKS and AK47. These were better built than the SKS. It is a cool cold war piece. $1530 shipped. Thanks, Gord.
