I guess it is one of the risks of buying from Germany that this kind of problem is a big problem. If the rifles been stripped then it cant be taken back anyway. New barrel is about £50, flog the old one to someone who uses a scope or wants to chop it (a chopped HW30 would make a great barn gun).
I don't think I'll do that - there is no guarantee that the new barrel will not be exactly the same.
It wasn't really evident using the standard rearsight, only when I put the peep on, so even mounting it up in a shop wouldn't have helped.
