I went to install my UM bolt handle, i turned the shroud out of the notch clockwise to remove the shroud, went back across the notch counterclockwise and went into the big detent without the tool or an allen wrench to keep the spacing. I didnt remove the factory bolt handle, i turned it back up out of the detent and put the tool in there, went back to the detent and swapped my bolt handle.

around 2 minutes in this video he says, youre gonna have a bad day if you go into that detent without a spacer. Have I damaged something? I got it back together and it seems normal.
