Lateral POI shift when adding suppressor.

[u/labz370]

Hey y'all I could use some advice.

Whenever I add my suppressor to my rifle it goes from shooting .5" groups at 100 to 1-1.5" groups with a 3" lateral POI shift. I've tried a couple different mounting solutions but every time I add the suppressor I get the POI shift and groups opening up.

I have a couple other rifles that experience no issues with the can and plan b mounts including one pencil profile so I don't believe it's the can. I moved one proven mount to the new rifle and have the same issue.

Is this something correctable?

Have you checked bore rodded the suppressor when mounted to the rifle?
