The ultimate design and features of an AR semi-automatic shotgun using a conventional gas-operated action which is located around the support tube that runs below the barrel. The return spring is also located around the same support tube which is concealed by an enlarged polymer handguard. The barrel can be very easily removed from the upper receiver. The upper receiver is manufactured from an aluminum alloy. The magazine release button mimics the M16 rifle location. The manual safety also duplicates the M16 style being located on the left side of the receiver above the pistol grip.
