Let's think this thru guys.... put on the thinking cap:
If it's as long with the stock removed as it is folded... it's legal to remove it.
If it does not make 26 inches FOLDED then it's illegal to begin with. <duh!>
Stock folded or stock removed it needs to have 16 inch BBL and be 26 LOA.
Makes no difference what length it is with stock extended.....
