Hi,
Do BRNO rifles still have a diaphragm or "C ring" in the front of the actions?
Thanks.

All the Brno ZKK's, CZ's, etc have the "C" ring however shank thread different than a Mauser. Also diameter differs when you get into the 375 H&H and larger cartridges. If rebarrelling pls ensure that smith is very familar with the Brno...not your std Mauser rebarrelling job......great guns if done properly...I own a couple.

Thanks.
My ZKK was made in 1966 and has the diaphragm. I was curious, and didn't know if it had been retained.
