Looked at a 16 ga SXS BL last Sunday at a flea mkt marked Ranger Chief on the case hardened action and little else anywhere on the gun. It was in super condition, but the seller warned all lookers that after firing any brand of shells it is nigh impossible to open and extract. Secondly, after the forend is removed, it can't be broken in the conventional manner. Seller suspects last owner took down and didn't reassemble properly. This is no Parker for sure, but it seems solid for $200 or less. Anyone know what this thing is and what might be ailing it? Top lever is way to the right, action tight and looks virtually unfired.
