Yep, that's what I understand. Dlask's and Dominion's are Non restricted as long as you don't put on a stock that brings it to under 660mm (which would include pistol grip). What is the OAL of Dlask's 8.5" with the regular stock? It's got to be pushing that 660mm as is.
That's what I say, and that's what should apply to any non-restricted gun. But if you're out having your fun with what you think should be a long gun, and all of a sudden someone with some authority comes along and says no that's a handgun, we've got a problem.
