Change the suppressor for another one with a different internal design in a PCP cal. 22, the point of impact will change.
FX effects of changing suppressor

I've got 3 moderators. A DFL Tanto, Tatsu and then a 3D printed one that is very light. I really only use them on my DreamTac. The only one that changes my POI is the Tatsu, which drops the POI about 1/4" at 35 yards. I don't leave them on either. I change them out depending what I'm shooting. If the other two are shifting my POI, I can't see it.

I have an uragan compact in .22. The uragan 2 has the same issue the original does. The shroud flexes down with anything screwed on the end. Simple solution is go to hardware store and get a nylon spacer, they make a size you barely have to sand the inner hole to get it to slide down barrel, when you screw on the shroud it now will be supported at the back with the spacer tightly sandwiched between the frame and back of shroud. Makes a huge difference, or did in mine. No POI shift with or without added suppressor on the end of shroud now.

I did the same thing a year ago in a U2 with a 700 barrel. I used an aluminum pad. But the main reason was the change of point even in transport. Very annoying but it doesn't concern me anymore. The stiffening of the barrel jacket in the U2 is for granted.

I am not seeing a POI change with any of my four .25 M-Rods when installing suppressors. I suspect that is due to the shroud to air tube support band near the muzzle. My Urban will shift slightly with a suppressor added but I note it has had the barrel band support removed. I remove and or interchange suppressors on the M-Rods as suits me. I hunt, not bench rest, so most of my shots are under 50 yards.
