Beretta USA 000521RR A400 RR Custom Xtreme Plus Full Size 12 Gauge Semi-Auto 3 1/2" 2+1 28" SB Platte River Waterfowl Vent Rib Steel Barrel Optima HP Aluminum Receiver Synthetic Stock Right Hand

The Beretta USA A400 RR Custom Xtreme Plus is a full-size 12 gauge semi-automatic shotgun purpose-built for waterfowl hunting and clay sports competition. This Rob Roberts Customs model combines Beretta's proven A400 platform with field-optimized components: a 28-inch SB Platte River vent rib steel barrel, Optima HP aluminum receiver, and synthetic stock engineered for reliable cycling in cold water conditions and rapid target transitions.

The 3½-inch chamber delivers versatility across magnum and standard 12 gauge loads, while the 2+1 capacity (two in magazine, one in chamber) provides sufficient firepower for most waterfowl and upland scenarios. At 10.8 pounds, the A400 RR Custom balances recoil management with maneuverability—critical for extended hunting days and repetitive clay shooting. The vent rib design aids sight picture consistency, and the right-hand configuration accommodates the majority of shooters. The Optima HP aluminum receiver minimizes weight without sacrificing durability in wet, corrosive environments typical of marsh and coastal hunting.

This A400 RR Custom Xtreme Plus is designed for serious waterfowl hunters and competitive clay shooters who demand reliability under field conditions. The synthetic stock resists weather damage and saltwater corrosion better than wood, making it ideal for offshore and marsh applications. Whether running sporting clays events or pursuing ducks in late-season hunts, this platform provides the semi-automatic reliability and shot-to-shot consistency that professionals and dedicated enthusiasts expect from Beretta's A400 line.
