If you’re a fan of the CZ 455 & 457 22 LR you’ll be an even bigger fan of the PROOF Research pre-fit carbon fiber barrels.
These are cut with a Bentz chamber, and headspace at .044″ +/- .001″ (depending on your action).
The 16.1″ barrels weigh 22oz, 18.5″ barrels weigh 25oz, and the 20″ barrels weigh 27oz.

The fit and finish are second to none! Grouping exactly how I was hoping even during break in!
