Not my gun and I have no relation to the shop, but I was just at C&S Metalwerkes in St. Charles, Missouri and they were putting out a 7xxx serial number SP-1.  It has the pinned receiver extension and Edgewater buffer, machined gas block etc.  It also has an early made in Japan 3x scope.  Their phone # is (636) 928-1511.  They had the gun and scope marked $2495.   Pretty nice looking gun, but I've got 3 early SP-1's and I don't need to be tempted!

Thanks for the alert, been a while since I was at C&S.  What area are you from, I'm south of St. Louis in Jeffco.

Price scares me away.... Are they good on negotiating? Someone could maybe get it little cheaper?

Montgomery City, out in the sticks.

I've had pretty good luck talking them down on a few things.  Ask for Ken, he's one of the owners.
