I use Trijicon scopes on a few of my hunting rifles and they are legal, so you shouldn't have any issues with your scope. I also have an extended box on a Creedmoor that I use antelope hunting. It holds six or seven in the mag box, when I called DOW, I was told that it was fine as it wasn't semi-auto and wasn't a detachable mag. You may want to give them a call to verify.
