Bidding without a condition report is a stab in the dark. The way I look at it everyone there knows what that gun is and about its true value, while you will be going off a 50 word description and a couple if photos. Then consider getting it shipped from there to your local FFL expense.
Those bargains, based on estimated bid prices, are not such a bargain when you add up all the money and time. It seems every gun that I bid on ends up selling for twice the estimate or more. You might get lucky but the odds are against it. So do it for the experience and not trying to get the steal of a lifetime.
