What’s Included
- JTS M12AR 12 gauge semi-automatic shotgun
- Cylinder-bore choke tube installed
This M12AR is built around a 20-inch 4140 steel barrel that is both chrome-lined and threaded for Rem-Choke tubes, giving you flexibility for pattern changes or muzzle accessories. The included cylinder-bore choke keeps spread wide for close-range work, while the threaded muzzle lets you swap to tighter constrictions as needed.
A four-position adjustable gas piston lets you fine-tune cycling for light 2 ¾-inch loads or heavy 3-inch shells. The system vents excess gas forward, helping manage recoil and maintain reliable function across a wide spectrum of ammunition.
The shotgun’s AR-style lower uses a standard selector safety, A2-style pistol grip, and a 6-position collapsible stock with a rubber butt-pad. The 13.75-inch length of pull adjusts quickly to different shooters or gear.
Up front, a free-float aluminum M-LOK handguard offers ample real estate for lights, grips, or other accessories while maintaining rigidity. A continuous Picatinny rail runs the full length of the receiver and handguard, simplifying optic or sight installation.
Weighing approximately 8 pounds and finished in matte black, the M12AR delivers a balance of durability and maneuverability, backed by an MSRP of $359.99 when new.
