I just picked up a Thompson Contender G2 in trade. Can you help me get a good estimate on it's value. Also, what brand scope rings do these look kike. There are no markings/numbers on the rings. Super 14 barrell in .223 Simmons Pro Hunter 4x32 scope Weaver #92A scope mount. Thanks in advance. Now all I need to do is decide if I want to keep it or sell. Wanna kill these ads? We can help!
