I would like to see what the rifles in question were 'capable' of in testing. Was this a case of a sub 12 rifle being nudged over the limit, or was this a case of a 30-40 ft-lb rifle being made so it could be turned down to 12?
In any event, removing the ability to adjust the rifle's power without dissassmbly seems to be a sensible thing to do.
