Introduced in 1903, the iconic “Humpback” was perhaps one of the most successful sporting arms ever conceived. It's no wonder, as it was a product of the legendary John M. Browning’s mind. This classic was one of the most flexible autoloaders of its day, able to shoot a wide variety of loads, thanks to Browning’s ingenious reversible friction ring. Before this point, most autoloaders were only capable of cycling specific loads. To boot, the Auto-5 would chew through shells rain, shine or choked with duck marsh mud. Despite Browning ceasing the production of the original A5 in 1999, they can still be found at a reasonable price, for shotgunners willing to do some digging for this true classic. A few years back, Browning also reintroduced a version of this classic using a short-recoil operated system it has dubbed Kinematic Drive.
