My mini's action didn't line up in its stock either. When the action screws were tightened down, the barrel was touching the left side of the barrel channel. It came with the polymer stock. I replaced the stock with the one from Oregunsmithing. I replaced the bottom metal with Jefferson Outdoor's hinged floorplate version.

I refuse to be victimized by notions of virtuous behavior.
