I have a couple of question specific to the CZ 527 that I need an answer to determine best donor gun for a .20 Extreme build.
1)Is there a difference in the external dimension (length) of the Magazine for .222 Rem and .223 Rem.?
2) Is there a spacer added inside the rear of the Magazine for .222 Rem?
