No takedown screw - ProMag Ruger 10/22 Tactical Folding Stock

I ordered this stock for another gun and it has the screw and then I ordered again and it’s missing the screw. I had to cut down my stock to get the metal that holds the takedown screw on an original polymer Ruger stock and drill a hole in the bottom of the pro mag stock so it could fit the metal holder snug to fit the takedown screw to give me the width I needed. Pro Mags Quality Department cant be the smartest if the package only has two items and they forget to put the screw the only other item for the stock.
