JTS M12AR Semi-Auto Shotgun 12GA 18.7" 5+1 M-LOK Handguard

The JTS M12AR semi-automatic shotgun brings AR-style ergonomics and modularity to the 12-gauge platform. This tactical shotgun features an 18.7-inch barrel and M-LOK handguard system that accepts standard accessories for customized configurations.

What Makes This Different

Unlike traditional shotgun designs, the M12AR incorporates familiar AR-15 controls and handling characteristics. The receiver accepts standard AR pistol grips and stocks, while the M-LOK handguard provides multiple attachment points for lights, lasers, and vertical grips. The gas-operated system cycles reliably with both 2¾" and 3" shells, delivering consistent performance across various load types.
