Just check alignment before firing.

Not necessarily directed at Doc Safari:
Obviously, anyone seeking to eff with mounts on a shoulder like this should seek advice from a competent gunsmith and/or check alignment before firing. Maybe consider a .30 cal can. Don’t blame me if you wreck an endcap on your $1,000 silencer after mounting it to your $499 rifle.
I swapped the MD on my PSA but didn’t even know to look at that. Even without knowing it, putting a suppressor on a PSA never seemed like a good idea to me.
