Mario, I'm virtually certain these are stock mirrors...I have a spare set given to me by a buddy off a stock MC21 that are identical. The mirrors of DUX sound exactly like mine, just really tight. So is there perhaps a lubricant of some sort that might help? I think I tried spraying something in the seam years ago to no avail. How much movement are others with stock mirrors able to get? In other words, what is normal/possible with stockers?
Thanks.
