Would a Douglas barrel be right hand threaded or left? What would be best way to remove threaded barrel from breech? The breech plug is stuck and gun has been sitting in this condition for 10 years. I have tried heat, it has sat with barrel full of penetrating oil, it has set with breech end soaked with penetrating oil. It will not budge. I would like to see if I can remove barrel from breech to access breech plug and restore. Any ideas????
