RE: selling on the net?
To answer your question, yes you can sell it on Ebay, or any of the other gun website mentioned without going thru an FFL dealer.
However; you CANNOT include any ammo or black powder, pyrodex with teh rifle. All ammo, black powder, pyrodex, etc. has to be shipped in a separate package. You need to check with the shipping company to see if they will even allow you to ship it. Some have restrictions on what they will and will not ship.
