You Sir. Get the nod for the win. Great stuff, best post.I don't own any currently in Canada but back at my property in the US I have 12 AR15 lowers 2 of which are registered as SBRs aswell as Colt M16A1 machinegun lower on top of those 12 and probably close to 25 different uppers. Also have 2 SR25s, a LMT LM8MWS-F and LaRue OBR 7.62 18".
