I just got a new host weapon for a 22 suppressor. Is there a way to verify that the suppressor is in proper alignment with the barrel?

Remove the bolt and/or breech, or whatever you need to do to look through the rear of the barrel safely. Screw the suppressor on the muzzle. Look down the breech. You should see the shadow of the suppressor, actually its endcap and possible baffles, and they should be exactly concentric with the muzzle circle visible down the bore.
