Not sure if this has been asked before but any chance you can get the 7.62 MRR and possibly with the Non restricted status? It would appear to have its own unique proprietary upper/lower and with the 18.6 barrel its almost screaming built NR for the Canadian market. There's also the C20 but it only has the 18 inch barrel. Ignore this if its been discussed already, tried looking but didn't see a thread.
