SRM Arms 1216 Rotary Magazine Features The SRM Arms 1216 Rotary Magazine is a revolutionary feeding system designed specifically for the SRM-1216 semi-automatic shotgun. This high-capacity magazine is constructed from durable polymer materials to withstand the rigors of tactical use while remaining lightweight. Its unique quad-tube design allows for a massive payload of 12 gauge shells in a compact footprint. Operation of the magazine is intuitive and fast requiring a manual rotation after every four shots to bring a fresh tube into alignment. This system allows users to keep the shotgun running through extended strings of fire without the bulk of a traditional drum. Having spare magazines on hand enables incredibly rapid reloads making it an essential component for the SRM platform.
