Hmmm. Is it safe to assume that the adjustable stock prohibition doesn't apply to pump scatterguns? I've got a Maverick 88 12 ga for home defense that I equipped with a folding stock/pistol grip that is length-adjustable when unfolded. I haven't yet taken it to the range, but have been wanting to do that. If it's verboten, I'd better just keep it home. Thanks.
