Designed by John Browning himself, the Auto-5 was the first successful semi-automatic shotgun ever produced. The A-5 features a distinctive high rear-end, earning it the nickname "Humpback." The top of the action goes straight back on a level with the barrel before cutting down sharply towards the buttstock. The A-5's unique adjustable friction ring set helps control the amount of recoil and the full choke ensures a tight pellet spread. The Ducks Unlimited Edition of the Sweet Sixteen has a high-gloss, high-grade walnut stock with fancy checkering and an exquisitely engraved receiver and trigger guard. This commemorative shotgun features an engraved receiver, a front bead sight, a ventilated rib, a cross-bolt safety, and a modified choke tube. Its wood and bore are in very good condition and its metal is in good condition.
