I have a mossberg 100 atr. I want a new stock for it, but no one makes them. I am thinking of making a new stock for it. Anyone want to give me some advice?
You can try adding bondo to your original stock and shaping it
till you get the desired contour and then have someone
cut you a copy with a duplicator out of a laminate blank
ot make a blank from birch plywood and wrap it with fiberglass
cloth and resin.
Look at this link. It is not that informative but it will give you and idea.
