This is a very nice all original Czech Vz52 Semi Auto rifle that was manufactured in 1956. Mechanically this rifle is in excellent working order. I have personally fired it and it shoots great.  This rifle has been professionally chambered to 7.62x39mm.  It was converted by removing and chambering the factory barrel, NOT USING A CHAMBER BUSHING! It has been headspaced properly and fired several times since the conversion.  I absolutely love the way this rifle shoots. A beautiful rifle that was built right and less than half the price of a real 52/57.
