I bought a used H&R Topper Deluxe 12 gauge at a local gun dealer and have a couple of questions. Is it the same as a regular Topper, just with a plated receiver? It seems that all the mechanical components are smooth but I don't think it has been tampered with (appears to have been shot very little and was well cared for). I know there are some H&R experts who can help and thanks in advance for your assistance.
