Reply To: ATLAS or HARRIS
Atlas rail, Only took about 10 minutes to install. I have a drill press, but not necessary. Marked my holes, Drilled through, Counter sink the back side with a spade wood bit so the nuts sit in flush and screw it together. Real easy.
This is how I did mine. You can get the T-nuts and Button screws at True Value Hardware for a couple bucks if you dont want to order them.
