The JTS M12AR 12 Gauge AR-Style Shotgun is a semi-auto with an 18.7-inch chrome-lined barrel, finished in black and supplied with two 5-round magazines (brand part no. M12AR-B1). It shoots both 2-3/4-inch and 3-inch shells and uses a 4-position gas system, so the action can be adjusted to the load you are shooting. A Picatinny rail runs along the top of the receiver for an optic or sights. JTS designed the M12AR for shooters who want an AR-style layout in a 12 gauge for home defense, range use or 3-gun practice.
