The Browning A5 Wicked Wing Semi-Auto Shotgun may resemble your grandpa's "humpback" Auto-5, but inside Browning has made dramatic innovations making the A5 a fast-cycling, versatile, recoil-operated, modern shotgun. The A5 still has the functional receiver profile the old humpback Auto-5 was famous for, that extends the length of your sight plane, though now the receiver is built from rugged, lightweight aircraft-grade aluminum alloy, making the overall weight of the shotgun lighter than the old Auto-5. Browning designed the A5 Wicked Wing specifically with the waterfowl hunter in mind.
