JTS M12AR-B1 18.5" Semi-Auto 12 Gauge Shotgun - Black$380.63
Availability: In Stock
The JTS M12AR 12ga semi-auto shotgun is a versatile, modern tactical shotgun built for hunters, sport shooters, and home defenders who want AR-platform ergonomics in a shotgun platform. At 18.5 inches, the barrel delivers the handling you need in tight spaces without sacrificing shot patterns, while the 5-round magazine capacity and semi-automatic action let you stay on target between shots. Whether you're running clay courses, hunting upland game, or setting up a reliable home-defense tool, the M12AR brings contemporary features to a proven shotgun design.
The 4-position gas system is the real workhorse here—it lets you dial in the action for different loads, from light target rounds to heavy buckshot or slugs, so you're not fighting short-stroking or over-cycling. The chrome-lined barrel handles corrosion and heat, and the Remington choke tube compatibility means you can tune your spread for whatever you're shooting. The aluminum forearm with M-LOK slots gives you a modern mounting platform for lights, grips, or other tactical gear, and the removable front and rear sights get you up and running fast out of the box.
Built-in Picatinny rail space and that M-LOK forearm mean you can configure this shotgun to match your mission without buying an entirely new gun. Two 5-round magazines come in the box, so you've got capacity to work with. The overall length of just under 38 inches keeps the gun handy in vehicles and tight quarters, while the semi-auto action keeps felt recoil manageable shot to shot.

Yes. The JTS M12AR is chambered for both 2¾" and 3" 12-gauge shells, and the 4-position gas system allows you to adjust the action to cycle reliably with either, so you can switch between them without losing reliability.
The M12AR accepts standard Remington choke tubes, giving you the flexibility to swap between different constrictions for various shooting distances and game.
The shotgun ships with two 5-round magazines, removable front and rear sights, and is ready to mount accessories on the Picatinny rail and M-LOK forearm slots.
The short 18.5" barrel and 37.99" overall length make it maneuverable in confined spaces, while the semi-automatic action, adjustable gas system, and choke tube versatility support both defensive and hunting applications depending on your load selection and barrel tuning.
