I got up early to call the east coast (where Numrich is) and got the order modified to take the ridiculously-priced screws off the order. Hopefully they will keep the rest of the order intact. I stopped by Fastenal and got the “cheap” screws. With them in hand, I drilled and tapped (8-32, not 8-36) the barrel for the quarter-rib, and ground the Fastenal screws to the proper length. (I would have had to do grind the “Factory” screws to length as well.) Since I don’t have an extra set of Ruger rings, I took the rings and scope off of my No. 1 chambered in .308 Win. The scope and rings installed without need for adjustment on the No.2, and the scope ‘comes to eye’ perfectly. I am going to get some 30mm Ruger rings, and put a Mueller 8-32x scope, (with 30mm tube), on this rifle and return this scope and rings back to the rifle from which it came.
