What’s Included
- SRM Arms M1216 12 Gauge semi-automatic shotgun
- 1 × 16-round detachable quad-tube rotary magazine
The manually indexed magazine adds four independent tubes that rotate in seconds, allowing rapid access to 16 shells without reloading. A removable magazine lets users carry spares for even greater on-demand capacity.
Controls are engineered for right- or left-handed operation. The safety, charging handle, and ejection can be switched, and the magazine release is ambidextrous, supporting smooth manipulation from either shoulder.
Built around a strong steel receiver and a lightweight polymer lower, the M1216 weighs about 7.25 pounds unloaded and measures roughly 33.7 inches overall. A 13.5-inch length of pull and rubber recoil pad aid comfort during rapid strings of fire.
The 18.5-inch 4140 steel barrel is threaded at the muzzle and ships with a protector. It is smoothbore with a true cylinder bore, ready for breaching or close-range work, and accepts both 2 ¾-inch and 3-inch 12-gauge shells.
Accessory mounting comes standard.
