I tried all of the normal places on the internet including that one. They and others advertise the carbine barrels but not the rifle barrels. This may well turn out to be my only non-working firearm. It is a simple barrel profile so I'll price out making one from a blank. I just think it will be more than the gun is worth. I'm going to join up at the Steyr club and see if someone might just have one.
Also, the bolt head has been welded closed and I assume the firing pin either removed or cut short.
