This two-round holder attaches with Velcro to the side of the rifle near ejection port. This little shell holder has saved my bacon on that one last shot more times than I can remember! In competitions, it can be a real match saver! In hunting situations or something where something greater is on the line, it can really save the day!
You must clean the stock with a good quality rubbing alcohol (91% preferred) and let that dry completely to prepare the surface for proper adhesion of the supplied industrial strength Velcro piece.
