JTS M12AR B1 12 Gauge 18.70" 5+1 Semi-Auto Shotgun

The JTS M12AR B1 is an AR-style semi-auto tactical shotgun chambered in 12 Gauge, built around an 18.70" chrome-lined steel barrel and a 3" chamber that cycles both 2.75" and 3" shells.

The action runs on a 4-position adjustable gas system, letting the shooter tune cycling for light target loads up through heavy 3" magnums. The receiver wears a blued/black metal finish and is topped with a Picatinny rail, making this shotgun optic ready right out of the box; a set of removable front and rear iron sights ships installed as backup iron sights.

Up front, the aluminum forend is equipped with a Picatinny rail for accessory mounting, and the receiver is set in a black synthetic stock configured for right-hand shooters. The muzzle is Rem Choke compatible for pattern control, and the shotgun ships with two 5-round detachable box magazines, giving it a 5+1 working capacity.

Tipping the scales at 8.80 lbs with an overall length of 37.99", the M12AR B1 hits a practical balance between a compact defensive footprint and a steady, range-ready sight picture - well suited to home defense, patrol duty, and tactical shotgun applications.
