S400 Silencer

[brickworks]

I have a standard Air Arms silencer on my S400 and accuracy has dropped off recently, today i removed the silencer and the POI was an inch higher, put the silencer back on and shooting an inch lower, have had a close inspection of the silencer and can't see any clipping, any advice please.

That’s totally normal to have a different poi in a vertical line when taking a silencer off.
The only time it wouldn’t be right is if the poi shifted to the left or right.
If that happens then you maybe clipping the baffles
