Because Not one of the pre-eighty one sears carry a serial quantity that may be definitively associated with a date of manufacture, there is not any solution to prove to BATF or simply a prosecutor that an unregistered pre-eighty one DIAS was basically made prior to 1981.
This method isn’t some large-tech gimmick—it’s mechanical genius with battlefield roots, and in Specialist fingers, it’s highly powerful.
