I have several SKS's one is a bastard with no matching numbers so preserving it is not any priority. It didnt come with a Bayonet , but it has the bracket in the barrel. I am wondering best way to take it off without heating the barrel or damaging it. I realize there is a pin in it but I do not have a press so would be done by hand and not sure that is how its removed without messing up the barrel. Thanks.
