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. This shotgun features a ventilated rib, front and rear bead sights, and a cross-bolt safety and comes with screw-in full and improved cylinder choke tubes and the original factory hard case. Its stock, metal, and bore are all in very good condition.
