I have a question for anyone with both Cz barrel sizes.
The bigger barrels being the .550 (shadows,sp-01,etc) and the smaller being the .500 (75b,pre b,compacts).
I'm wondering if both these guns use the same barrel bushing with the only difference being the I.D. of the bushing.
Should be able to tell by using a pair of calipers or just looking at the bushings with both guns side by side. Thanks TC
