The JTS M12AR-B1 is a modern semi-auto 12 gauge shotgun built for shooters who want AR-platform ergonomics and versatility without the AR-15 price tag. With an 18.5" barrel, short overall length of roughly 38", and a gas-operated design, this tactical shotgun handles everything from sport shooting to home defense. The four-position gas system lets you tune performance to your load—whether you're running light target loads or full-power buckshot—so you get reliable cycling and manageable recoil across the board.
The M12AR-B1 comes ready to customize. A Picatinny rail on top accepts your choice of red dot, scope, or other optics. The receiver is drilled and tapped, and the chrome-lined barrel resists corrosion and wear. The shotgun accepts Rem choke tubes (cylinder choke included), so you can swap patterns for different game and ranges. Two 5-round magazines ship with the gun, giving you practical capacity for competition, hunting, or tactical use.
This is a no-nonsense shotgun for the hunter or sport shooter who values adjustability and modern handling. The compact profile makes it manageable in tight spaces, while the semi-auto action delivers speed and follow-up shot capability. If you shoot standard 2¾" or 3" shells, the M12AR-B1 will cycle both—just dial in the gas system for your preferred load and go to work.
