Quite correct when stated that this is what the CZ should look like . I liked the bolt shroud set up of the Brno ZKK series ;the bolt handle would have been preferable to this one but was livable .Unfortunately when Brno moved to the new CZ factory they chose to install that hideous bolt shroud on the new CZ 550 series rifles. The firing pin setup remains the same (I actually have installed a CZ firing pin in a ZKK Brno but as the new CZ pin is hidden in that most hideous new bolt shroud when installed in a Brno shroud it sticks out unfinished in the rear of the ZKK shroud .I threaded the pin and installed a finished knurled cap to complete the job
