I'm sorry but I don't see what the downside of having it checked out by a qualified smith before accepting it is. You haven't had it checked out by an independent smith at all. All you have to go on is what his guy says. If it were me I would have it checked out before accepting it no matter how perfect it seemed. Granted to ejector problem might be minor and only on one set of barrels but what if there is something else wrong that hasn't been caught yet. There have been enough threads on used dr deals gone wrong to have it checked no matter how good of a deal it seems like. It is still almost 20K no matter how you look at it.
