As the others have said there are a lot of variables.
My YHM Phantom Stainless shows no shift when I take it off one rifle and put it back on.
I have a newer YHM Resonator K...I have noticed some shift. Same muzzle brake adapter so I have to chalk it up to the suppressor. I noticed it worse when it was new...now that I have shot it more it seems to have gotten more consistent.
