Shooter50,
I don't know if this will help you, but it was the path I chose with my Renegade. Its a blank and all you have to do is measure and drill. However, I would consider the hammer clearance on the scope. I went with a sightmark AR compact 3x9x42 scope and a medium ring. This will allow you to mount a scope without drilling holes in the rifle as long a you use the rear sight mounting holes and the first screw hole on the tang. Just a thought.
