SRM Arms Model 1216

The SRM Arms Model 1216 is a delayed blowback semi-automatic shotgun with a 16-round detachable magazine. Designed for mobility, it is light and short and intended for home defense and law enforcement.

Design details
The most unique feature of the M1216 is the detachable magazine. The magazine which runs parallel to the barrel is made of four tubes, each with its own spring and follower. Each tube can hold four 2 3/4" or 3" shells for a total of sixteen. When inserted into the gun, the operator can flip a switch and manually rotate the entire magazine to choose which tube feeds into the receiver. In a tactical application, this would allow the operator to switch between different types of shells to adapt to a changing scenario. Once the magazine is empty, you can press the release switch to drop the magazine and replace it with a full one.

The M1216 has a polymer stock to reduce weight and a steel upper receiver. The manual safety, charging handle and ejection port can all be removed and relocated to either the left or right side of the receiver to accommodate the operators preferences. Picatinny Rails line the top and sides of the shotgun allowing a wide variety of attachments such as sights, lasers, and flashlights to be used.
