Like the title says. Does anyone have experience fitting other brands of standard M16/AR15 magazines in the MR1. Also where is the best place to buy them in Canada. I already have some of the 10 round Rock River Arms magazines on order and was considering getting some of the Magpul PMAGs from Questar. I have read conflicting things about magazine compatibility with this rifle. If anyone has any personal experience it would be greatly appreciated.
