Putting on a factory barrel shorter than 470mm when the gun is registered for a longer barrel doesn't change the classification but does cause the gun to be different than the registration certificate. This doesn't trouble me as I put on the 14" barrel on my 870 even though it is registered over 470mm.
What is interesting about that notice is the need to inform the CFC when there is a modification to "gauge." Perhaps at the next big skeet shoot the CFC should be called each time a competitor changes his subgauge tubes. "Hi there, finished the 20 gauge event and put the 28 tubes in so change the registration on my gun. Call you back when it's time to shoot .410. When I go home I'll have the 12 gauge barrel on so I'll call you then too."![]()
But did you noticed that you have 30 days to report the change LOL.
So, if within 30 days you put back the original gauge back on, by law, you don't have to report the change.
Strange situation to say the least.
I believe that the intention is to report a permanent change of the barrel to a different caliber but your situation did not come to mind when the regulations got drafted.
