Hell, I'd LOVE to be able to take my Colt 20" bbl AR out after coyotes, gophers, whatever, here in Southern Alberta.
At one point, about 25 years ago, we could do just that.
However, since it's on the Restricted list (despite the fact that it's 39" long and about as concealable as a 3'3" length of 2x4) it ain't gonna happen, unless I want to go in front of a judge.
IF, if, we could get permanent pivot pins installed, there may be a remote possibility that AR's with said pivot pins and 20" barrels could be removed from the Restricted list (and Wendy's ilk would have a heart attack).
It's only on the Restricted list because a) in the eyes of the CGC it's REALLY scary-looking, and b) since it's a modular firearm, the owners CAN get uppers with extremely short barrels (7.5") which would automatically put them in the Restricted category, even before C68 came into effect.
