I purchased a Rossi Combo at a show recently,3 barrels,17 HMR/270 Winchester/50 cal. muzzle loader.All looks new unfired,can't pull hammer back on any of the 3 barrels,all the barrels will go together but hammer won't pull back to cocked position.I called Rossi,very nice service rep I talked to.I gave him the serial number on the reciever,said the reciever was made in 2002,and was factory fitted with a 12ga/22 long rifle.He said it could be sent back to factory and refitted.I'm not sure I want to do that,is there much of a market for this stuff to sell it out.I paid $225 for it,I see barrels for $100.+ on auction sights each.Its all like new,I'm just hoping to get my money back.I don't know which way to go lol
