I've been toying with the idea of installing the Archangel stock on a pre-ban M1A with the dreaded receiver ridge on the right side. For those who have taken the challenge, was it worth the trouble? Did you trim the stock to fit or did you bed the receiver to the stock? Were you still able to fit the trigger assembly without having to shim it if you did trim the stock? Any pictures of the work? I checked many posts but couldn't find any good information with fitting this specific stock on the ridged receiver.
