Hi , I know a Vietnam Vet that has a SKS that he brought back , my question is he is looking to sell it but doesnt have paperwork for it and I do not believe he has any form of current gun license . Can he legally sell it to someone , if so how does he go about doing this , and could the buyer just fill out a FA 10 form as a new register since it has never been filed in the U.S ? Bill of Sale? Or is this something that he shouldnt even have posession of , I believe he also has some other rifles from sometime ago when I think you didnt technically have to register guns , you could just go into sears and buy them , what can he do with those? Any input would be helpful , Thanks
