that is putting it "mildly"! in the case of firearms law, there is no sensible application, usually, since it is usually drawn up by mandarins, to suit the purpose of "politicians". the politicians are only interested in getting re-elected, so they listen mostly to the self interest groups, that make the most noise.I got "pinched" by this technicality in Canada years ago. When I got my little Oviedo saddle ring carbine (almost identical to the Swede 94) there were no restrictions on such weapons and also no requirement to register long guns.
That ALL changed a few years later when there was a compulsory long gun registry...miraculously...now my carbine was a "restricted" weapon because of the barrel length. My Swedish sniper rifle also was categorized as a "restricted" weapon because it had the word "SNIPER" as part of its nomenclature. A scoped rifle (even with better optics), without "SNIPER" in it's description was not in the restricted category!!
Public policy can get pretty wonky?!?
