Thread: Brno Fox query

Hi everyone, I have an old Brno Fox in 222, shoots ok but the barrel sadly has a fair amount of old pitting, so it’s not going to get any better, and I’m keen to renovate. I’m aware that the CZ 527 is a newer version, can the CZ barrel be screwed into the Fox receiver? I’m guessing the action will be longer on the 527 as it’s a 223, but are they compatible any other ways? Thank you!
