Just a quick question. I have a buddy who has a CZ 550 in 30/06 and I have a 30 cal Shilen barrel pre threaded for a large ring Mauser that he wants to screw on his rifle and chamber to 308. Are the barrel threads on the 550 the same as standard 98's? Are the 550 Safaris the same barrel thread as 98's? Thanks for your help.

I don't know the answer and someone who probably does will mostlikely respond before Monday but if you email Doug (Shilen) he'll certainly be able to answer your question. He's usually pretty quick to respond.

No, they are not the same. The CZ is a 2mm thread pitch (roughly 12.7 tpi)while the mauser is 12tpi. Regards, Bill

The M-98 also have a 55 deg. thread not a 60 deg. that Brno and CZ uses.

the 98s are a bred unto themselves, as some May have 55 and some may have 60... of some in my stash, the vz's are all 60 and the brazilian is 55..
