Purely a guess, but given that they shipped it assembled without a rod tube it sounds to me like you got a floor model from one of the stores. Perhaps the distribution center was out of stock, and so they fulfilled the order from a store that had the model. Now the store presumably has the corresponding tube behind a counter or in the back, but sounds like the employee who processed/packaged the order didn't know or care to look for it. Those are all just guesses on my part, but to me seems the most likely explanation. In any event, you definitely should have received a tube and so you should ask for a replacement or for them to ship the missing components separately. As for the rings, that's what they show on their website. Good luck.My CGR 3-weight arrived today. It is shipped fully assembled (3 piece) in a big cardboard tube. There is no case or rod sock. The reel seat does not have threaded rings, just rings that slide over the reel foot and hold by friction (nostalgia, as a kid I had a cheap spinning rod like that.
