I would like some information about these two rifles. First thing I would like to know is did they shorten the barrels of VZ-52's to make the 7.62x39
52/57 model or did they install new barrels. If you have both rifles this would be easy to tell as the 52/57 should be about 3/4" shorter due to the
difference in case taper between the X39 and X45.
I have read that this rifle after being modified to 7.62x39 did not have the accuracy of the original 7.62x45 loading, is this true?
