SRM Arms M1216 12 Gauge 16-Rd Black Polymer Shotgun Magazine

The SRM Arms M1216 spare magazine is a factory 12 gauge 16-round replacement designed for the SRM Arms Model 1216 semi-automatic shotgun.

Built around SRM's signature rotating quad-tube design, this magazine holds sixteen shells across four separate tubes of four rounds each. The indexable tube carrier lets the shooter rotate to a fresh four-shot tube between reloads without dropping the magazine, dramatically reducing reload time on a fighting shotgun.

The magazine is molded from durable black polymer and accepts both 2-3/4" and 3" shotshells. Dimensionally identical to the magazine that ships with the SRM 1216, it serves as a perfect spare or backup for keeping the platform running in tactical, home-defense, or training use.
