Hey guys, I have a '67 Wingmaster and I wanted to save the walnut and put on some Hogue stocks. When I tried to remove the stock screw with my large screwdriver, with a bit of force, half of the screwhead snapped off. This was surprising to say the least. But now I'm wondering how I can get the stock off without destroying the walnut stock. I don't really want to pay a gunsmith as I want to use the polymer stocks. Any advice?
