Is it possible to have information about the changes to be done in a RS upper receiver to fit a PTW / CTW properly? Do any one of you know someone who does it?
Thanks a lot for any info provided!

You open up the rear of the upper to 1" and cut a keyway for the cylinder. You also have to cut a notch for the sun gear on the right hand side.
I have an Aero Precision COP monolithic upper on one gun now, and I have cut a Sun Devil slick side upper several years ago. You can do it with a Dremel. It takes a couple of hours.
