When you find one now in close to as new condition, you pay what you have to pay. I found mine in that condition in early 2017 and paid $350 out the door and was happy to find it. In my opinion that would be a steal today.
Completely agree. To the original poster, if I was buying abother 5 1/2 bull barrel MK II, I’d try and get one that was drilled and tapped for a rail. Mine isn’t, and as much as I love shooting open sights, my ageing eyes don’t work like they used to.
