The Archangel shell carrier mounts to the side of the shotguns receiver. Precision molded polymer shell carrier and aluminum mounting plate securely hold 7 additional rounds for fast tactical reloads of the magazine tube. A patented retention adjustment system allows for the individual tension adjustment for each shell allowing the user to fine tune the shell carrier for specific ammunition and the level of retention required. A rubber molded gasket fits between the mount and the receiver to protect the firearms finish.
