Does anyone here with experience working on Brno and CZ rifles have the receiver/action and barrel thread dimensions for these rifles? I haven't found an easily accessible reference for these.
Thanks

Brno/CZ receiver and barrel threads

CZ 527 Miniture (223): ?
CZ 550 Standard (30-06): M26x2sp3 thread.
CZ 550 Magnum (375H&H): M26x2sp3 thread.

Brno ZKK 600/601 (30-06/243): ?
Brno ZKK 602 (375H&H): ?

Brno 468 (223): ?
Brno ZG47: ?
Brno 21/22: ?

CZ 527 is .890 x 1.25mm pitch

The Mini mk x is .853 x 1.50mm pitch

Don't know about the others. I haven't rebarreled them but I have many of the other two.
The 527 is my favorite. As far as I'm concerned the mini is rough as a cob and therefore junk.

Not asked, but the 452/253 rimfires are 1.25mm pitch threads.....20mm diameter if I remember right...and I just re-barreled one yesterday....

Thanks for the input. I was wonder about the 452s, but do not have a project involving one. May come in handy sometime in the future.
