Hello I trying to remove the buttstock and iam unable to losen the top screw on the under buttpad any idea all Ian doing is striping the screw
It is also called a hollow ground screwdriver. The shape is very different than a "craftsman" screwdriver. It looks like a round rod/shaft that has two sides of the tip milled to form the blade. The tip has no taper (face or sides) and it grips the bottom of the slot where the screw is the strongest. Brownells and other gunsmith suppliers sell them.
Forster products has some good pictures and explanations as to why these type are best.

I don't know what number bit is the right one for the stock.
