The SRM Arms 1216 rotary magazine gives you serious capacity from a 12-gauge platform. Built to feed the SRM M1216, this 16-round drum holds enough ammunition to keep you in the fight during extended shooting sessions at the range or in the field. Unlike traditional tube magazines, the rotary design cycles reliably and lets you load all 16 rounds without the long, slow process of stuffing shells one by one into a fixed magazine.
Made from tough polymer, this magazine is engineered to handle the pressures of 12-gauge loads while staying lightweight enough that the added capacity doesn't bog down your shotgun. The black finish matches most modern tactical or home-defense builds. If you're running an SRM M1216, having a spare high-capacity magazine means more time shooting and less time reloading—critical when you're training or competing.
The rotary mechanism is the real advantage here: it distributes rounds around a central hub, so feeding is consistent shot after shot. No binding, no jams from shells stacking unevenly. That reliability matters whether you're running drills at a 3-gun match, running clay, or staging your shotgun for home defense. And at 16 rounds, you're looking at double or triple the capacity of a standard magazine tube.
