If you have a RR you don't need to machine anything on it. Those are instructions for someone who can legally make a new MG.
You will need to shorten the pins that hold the trip bar in the upper. Only takes a few seconds with a grinding wheel before you put them in.

Well, the Description further states:
!!!!PMM WILL NOT INCLUDE INSTRUCTIONSOR ANSWER QUESTIONS ABOUT INSTALLATION OR MACHINING ANY SELECT FIRE COMPONENTS!!!!
I'm not "Carnack the Great" and I'm not a Class III/SOT. There's no way I'll spend $1,800 to $2,000 for and upper and another $130 for a trip kit without some sort of definitive statement from the manufacturer(s) on their website(s), not just chatter on an internet website. And there's no way I'll grind or machine my Colt M16 lower. The vague, indefinite language that I see leads me to believe that it is likely that some grinding and/or machining of a RR may well be required.
MHO, YMMV, etc.
