Good news. The damage isn't as bad as I first thought. With the extra width of the no-peep bracket, the screw wasn't really long enough and only the first 2 or 3 threads were engaging. That is why it was so easy to strip. Fortunately, Bowtech taps threads all the way through the riser so by just running in a 10-24 tap to clean up the threads and using a longer screw, the problem was fixed.
I really have to say my archery shop is the greatest. They are closed on Sunday but I called him up anyway to ask some questions and he let me bring it in anyway. He looked it over, identified the problem and fixed it for no charge. He even re-served my string (factory serving was already beginning to separate?), let the draw length out 1/2" and re-tuned my bow. Now that's service, LOL.
I bet he reads this website so now he will no who I am
Now another question about the no-peep itself: I have it adjusted vertically so that when I draw my bow, anchor, and touch my nose to the string, it is OK vertically but it needs to swing right a little to give me that perfect bull's-eye. There doesn't seem to be any windage adjustment however. How do you adjust it right-left?
