I have a 1987 4" 686-1 pre-lock in pretty good shape, that I would be interested in trading for a newer 6" post lock that is factory tapped for a scope. I want to scope a 6" 686 and don't want to ruin a pre-lock by tapping it.
It isn't for sale, (I'm saying that so there isn't a bunch of "how much do you want" posts) but if you have what I want to trade, shoot me a PM.
