What is the Hole spacing for A commercial FN ? Is it the same as a Husqvarna, Interarms Zastava ?
Usually a Weaver 45 and 46 will fit. The rear holes should be .5" apart. There may be exceptions. My very early commercial FN came with a Buehler one-piece that didn't match a regular Redfield or Leupold. Only one rear hole was drilled, so I had another one put in for two-piece bases.
Never seen a blind mag on an FN. If it's really an FN (Made in Belgium), you can probably find a slide-off unit pretty cheaply if you don't want to spend a bunch. It would certainly simplify replacing the stock.
Pics would be nice. Never seen or even heard of the White Stores version.
