What long action models had detachable box magazines? I have a used XLR stock on the away that will fit a long action with mag. The 3 long actions I have are not box magazines. I am thinking I can put one of my current ones in and shoot single shot which is no problem. I have one that has a plate welded to the bottom of the mag opening making it a single shot only it might work but it has a 223 barrel that is shot out but I would rather use the stock for either my 6MM BR or .308.
