Not an inappropriate post at all, though, if you wish to sell it and have a price in mind, then the best place to post would be the Classifieds forum here.

I am not at all sure about how complicated it would be for you to sell the rifle here in the US - imports, from what I understand, are difficult unless you know a dealer who is experienced in customs and other mandatory procedures. In any case, we do have members here who have imported guns and they would post and advice you shortly.
