Lothar Walther makes a barrel with the correct profile and threaded ready for the 527 (see them on ebay for around 399). The threads are metric but I do not remember the dimensions. The one I had done the smith uses CNC machines and has all that saved for doing more just like it. See the Grendelized CZ 527 thread for more on my rifle.
The barrel has if I recall correctly 3 different tapers to fit the stock, straight, 60 inch radius taper then straight taper to muzzle.
