I've had my 457 for about 14 months now. I've estimated to have put around 6-7,000 rounds through her and kind of interested in taking the bolt apart to clean/inspect. Are there any videos out there? Anyone have any experience? Thanks
Check on rimfirecentral.com in the CZ/Brno section, top of the page, STICKY - Do we have a definitive thread on 457 bolt disassembly? It is nothing overly crazy as a matter of fact quite simple.
