Did Brno / CZ keep the barrel thread (receiver thread) the same in the model 1, model 2, semi auto & CZ 452 ? Are the barrels interchangeable between the models? I have a sick model 1 Brno & it need a new barrel, can I use a model 2, semi auto or CZ 452 barrel?
 
Rod,

As far as I know the rimfire bolt actions are the same thread...I have fitted early Model 2 barrels to CZ452's with no headspace adjustment.

What size are the thread's on those CZ452's just wondering,cause I done one for my bro-n-law acouple month's ago, we set the barrel back a 1/8 of a inch and rechambered it. It was metric thread's of some sort 17 or 18 MM, I can't remember the thread pitch (I think it was .100 or .125). YBRF Rambo

PS: I could'nt find no tap's or die's in that size.
