Thats a sensible approach. I considered the quick detach rings but whatever scope ends up on the M1A its likely to stay right there. The 4-12 is currently on a CZ 521, and its not ideal for that gun. The 2-7 arrives tomorrow and I'm thinking that will be a better match-up with the CZ, and the Rifleman can live on the M1A. Nothing is set in concrete though..
