Moe,
Based on my experiences, I think I would prefer to see the barrel before it arrives in the mail and the deal is done.
Had one arrived by mail that looked like the offered barrel with the pock problems, I would have had to re-mail it and wait on another until the replacement came back.
TC has been very, very good to me and solved every one of my problems like missing screws, but it sounds like the tradeout norm is multiple weeks and I really don't want to wait that long should the need ever arise.
I do appreciate what you are saying but as picky as I am, I will most often want to see the barrel before plopping down $250-350. If I ever trade for one on line or over the phone, I will ask lots of questions before committing.
Mike
