The Beretta AX800 Suprema Optifade Marsh 12 gauge is a gas-operated semi-auto waterfowl shotgun with a 26-inch barrel and a 3.5-inch chamber (Beretta part no. JAX8MR16). Beretta calls the AX800 Suprema the most advanced waterfowl shotgun it has built, pairing the B-LINK Pro gas system with Steelium Pro barrels and a Kick-Off Pro stock. The polymer receiver is weatherproof and carries an integrated optic mount, and the stock is fully adjustable for length of pull, drop, cast, cheek piece and grip. It was designed for the blind, the boat and heavy magnum loads, and the Optifade Marsh finish suits wetland hunting.
