I used an angle block and mag based dial indicator.  Clamped the barrel end into the angle block.  Checked bore to block dimension in two quadrants.  Measured against a gauge block on each move of the mag base.


Don't see why a suppressor that is bottomed out on the threads without going against the shoulder automatically means mis-aligned?  It may not repeat position as well, but it doesn't seem to guarantee being cocked.  A gauge rod would be a good quick check of that if you had a rifle threaded like that.  I think I would want to check that before shooting anyway.  Don't most (.223) suppressors about .030 larger than the bore?
