I have a CZ 527 7.62x39 Carbine. It is accurate, functionally sound, inexpensive to shoot and a fun gun to own. As an oh by the way, the CZ has a .311" bore while many, if not all, Rugers are .308" bore. I am running in my CZ .310" 123gr SSTs over H4198 and it will shoot 5 shot groups around an inch all day long. CP.
