Cool, similar idea to the Troy PAR. If someone could design a similar rifle with a proprietary magazine, upper, and lower that will not fit any semi-automatic firearm, it would not be subject to the magazine limitations of semi-automatic in Canada, and you could have anything up to and including a drum magazine on the thing. An shotgun example is the 11 round magazine on a Dagger SAP-6. Perhaps Wolverine and Kodiak could partner with an American manufacturer interested in bypassing magazine limitation laws in some American states to develop such a rifle You could make it compatible with the butt-stock, pistol grip, and trigger of the AR-15. You could probably modify the WK180-C design, but you would need to be careful to make the upper and lower completely incompatible with the with the WK180-C; if you could fit the lower with the custom magazine on a existing WK180-C, that would make it a dual-purpose magazine, which would render it subject to the five-round magazine size limitation and nullify the whole exercise.
