A Glue-On Base Pad increases your stock magazines' length by .360 inches to provide positive seating without getting too long for practical use.  The key to installing glue-on base pads is to roughen and degrease all contact surfaces prior to gluing.  Apply a thin film of quality contact cement (we use Barge cement) to both surfaces, let it dry, then firmly press the base pad onto the magazine.  Properly installed, the base pad will stay on forever.
