Update - the scope mount arrived, and I mounted it on my '03 Springfield. 2 problems became immediately apparent.
1 - With the mount in place of the cutoff switch, you can't remove the bolt.
2 - My Redfield peepsight couldn't lower enough to get back to zero - the mount was in the way. If I had a barrel mounted rear sight it would be fine, but that's not the case.
Bottom line, it's off the rifle and I'm staying with the peep sight. I have another rifle with a scope on it, so not a big deal. The big thing for me with a scope is being able to use the iron sights as well as the scope.
Thanks again for the input guys - much appreciated.
