Home Forums Hunting & Shooting Hunting Rifles CZ SAFETY NOTICE REGARDING CZ 600 BOLT-ACTION RIFLES

"CZ has learned that if the barrel is improperly installed, it is possible that the rifle could still be fired, but potentially result in a failure."


Given that it uses a barrel extension type system where the lugs lock into the barrel assembly not the receiver....really makes you wonder how this could really be a problem. My only thought would be that if there were some different critical dimensions for the different bolt heads, maybe with the right combination you could get the wrong bolt head to lock in enough to fire?

I doubt that was going to be much of a market. It’s one thing to make a slip-fit rimfire barrel when the action locks on the root of the bolt handle, something else when lug mortices have to be machined into the barrel.

As I recall from pictures, the barrel had a flat that aligned it with the receiver, then the screws clamped it in place. Possibly there was no interlock to prevent the firing pin from falling if the lugs weren’t seated. The extractor may hold the cartridge against the bolt face. Still gotta wonder how this made it into production like it is.

Edit:
Just occurred to me that maybe the rifle could fire with the wrong bolt head installed.

Interesting that the euro site says they will offer barrel changes at service centers, but the US site doesn’t.
