Thanks very much for your input. So it sounds like those holes in the top of the receiver can accommodate a rail or mounts specifically made for them. So if I get a rail, then I need to get scope rings that attach to the rail and if I skip the rail, I need rings with a mount to fit the drilled holes in the receiver. Sound correct?

Also, great idea on reactive targets. That will be fun. I will definitely take time to report back on the t3x 30-06 experience.
