The Tavor TS12 12 guage shotgun features a unique patented “bullhead” bolt locking system, specific to the TS12. The 18.5” smoothbore barrel with a 3” chamber is fed rounds through a tubular magazine system that automatically loads the next round when the tube is rotated in position. The muzzle threads are internal and compatible with Benelli/Beretta choke tubes. The gun ships with one choke tube. Compact in length (only 28.34″), the TS12 has a one-piece, full-length 1913 Picatinny top rail with M-LOK receptacles integral in each side of the forearm of the shotgun body, allowing multiple placement possibilities for the addition of accessories.
