Recurve, what the other guys said, and don't rely on the chrome barrel being a barrier from rust. If it is only water, and no Black Powder, it is very minimal rusting. But if you have black powder, and it gets moisture, from humidity, or where ever it "WILL" rust. Stainless steel, reacts differently to black powder rusting, or sulphuric acid, which is what you get when sulphur and water mix, and sulphur is a component in black powder. Stainless will have very little surface rust, but it will pit really bad. So do as Dane said, clean it extremely well !! I use hot soapy water, and remove the barrel, and the nipple, and stick the barrel down in a bucket of hot soapy water, and take the ram rod, and put a piece of cloth on it that will fit somewhat snug, and stick it down the barrel, and put the barrel in the bucket of water, and start pumping the ramrod up and down, and it will act like an old pitcher pump, and start drawing the hot soapy water up into the barrel, through the nipple insert, and you can bring it all the way to the top. Do this for at least three to four minutes, or longer, then run a clean rag down the barrel, and it it comes out sooty, or streaked, repeat the hot soapy water process, and then when a clean rag comes out clean, put the barrel down into a bucket of hot clean water, and do the pumping action with it, till it comes out clear, and no soap. You can just pour hot water down it also, to clean the soap out. Then let sit upside down, for a few minutes, and then run a clean dry rag down it, and then when it is dry, run a lightly oiled rag down it.
You have a lot fun ahead of you. Dirty, but fun!
Don't forget to clean the nipple also. And it would be a good idea, to get an extra nipple.
