Bjorn I have done it to both 6.5 and 5.56 bolts in both cases I left it longer than what the instructions said. I think that I removed 2 or 3 coils depending how you look at the spring. I wanted to make sure I didn't take too much off especially since the spring is kind of hard to hold securely,as you probably found out.
