The original Save-It Shell Catcher. All-steel shotgun shell catcher prevents empty hulls from being ejected through the receiver opening. The catcher holds the empties for easy removal. Works with all 12-gauge semiautomatic shotguns. Attaches to the gun's receiver with double-faced tape. Padded tape keeps the metal away from the gun. No movement or vibration to scratch the finish. Adjustable for different loads and guns.
