The shotgun market has seen a considerable evolution in the last decade or so with various models incorporating multiple barrels, automatic fire modes and other features typically not common to this line of weapon. SRM Arms produces the Model 1216 shotgun, a 12-guage semi-automatic design sporting a polymer stock, Picatinny accessory rails and a four-tube magazine.
Perhaps the most notable quality of this firearm is the aforementioned magazine consisting of four, spring-loaded tubes holding the shells in a rotary-style arrangement. The tubes are mounted in parallel to the gun, just under the barrel assembly, and contain up to four 12-guage shells (model dependent). The shotgun, therefore, can carry a maximum of sixteen shells and each tube can house different shell types to suit the mission need. The operator retains complete control over which tube is feeding the subsequent shells into the action during fire. All controls can be flipped for left-handed shooters and the Picatinny rail mounts support various tactical accessories.
There are three major variants in the Model 1216 lineup and this includes the base, full-length Model 1216. The Model 1212 is given a shortened barrel length (13") and has its overall length accordingly reduced to 27.5". However, the ammunition tubes hold only three shells apiece so overall shell count is reduced as a result (to 12 shots). The Model 1208 is a shorter-barreled version of the Model 1216 and has a 10" barrel with overall length reduced to 24.5". This, therefore, reduces the ammunition capacity again to eight total shells in the four available tubes. Weight of the three guns is 7.25lb, 6.75lb and 6.25lb respectively and all feature the same semi-automatic , roller-delayed blowback system of operation. Shot types supported include slugs, #00 Buck, trap loads, game loads and specialty rounds (in 12-guage, 2 3/4" and 3" shells per manufacturer specs). Disassembly is via a push-pin.
