I wonder how a suitably qualified/licensed dealer will bring an earlier U.K. spec deac up to the new E.U. spec? How is he going to drill the holes in the bottom of the barrel, as per E.U. spec, when there is already a slot cut through it? Is he going to have to fit a new barrel so he can re-deactivate it in the new way, weld up the slot then drill holes through it or perhaps just drill holes through thin air???
