I've done it, but can't remember how many it held in the belly. If I was doing it again, I would stick with the lightweight 1 piece bottom metal mainly because the Edge stock with a blind mag on a M70 has more square corners...the bottom metal makes it seem rounder when carrying it with one hand under the action.
Still have a MRC1999 blind mag that should be ~ the same that I'll try to check later.
