Just so you know I have had Several M600 s and M7 s drilled and tapped for the 4 th screw and itās a relatively simple job to doDoes anyone know when Remington began drilling and tapping the rear receiver bridge for a 2 screw scope mount instead of the 1 screw?
Sorry BuddyI am not in need of that done Jim. I am trying to get a ballpark on when this rifle was manufactured. It has a replaced barrel.
