Volquartsen 10/22 Stock Take-Down Screw This is a precison Allen Head stock screw for your Ruger 10/22 Stock. The Allen head serves two purposes. First, it doesn't get buggered up like slotted head screws. Second, it fits torque wrenches so you can set the stock tension to be the same every time you remove and re-install your stock.
