The JTS AR-style 12 gauge shotgun is a semi-automatic with an 18.7-inch barrel (JTS part no. M12AR). JTS built it around a 4-position gas system, so the action can be adjusted for the loads you run, and a chrome-lined barrel that takes Remington-pattern choke tubes. An aluminum forearm with M-LOK slots and two side plates, a Picatinny rail and removable front and rear sights make it easy to set up for home defense, range work or the field. It digests 2-3/4-inch and 3-inch shells and comes with two five-round magazines, so you can start loaded for the way you plan to use it.
