Built on the SE122 frame, the SE122 Tactical shares important characteristics, including a strong but sensitive gas system that cycles reliably with a wide range of loads, and an action bar milled from solid steel. In addition, the SE122TAC features an ingenious, self-adjusting gas valve. For extremely heavy loads, excess gas pressure is vented forward and diffused. For light loads, the valve remains fully closed, making all available gas pressure available for reliable cycling.  The result is the most versatile gas system we have ever produced, assuring reliable operation with the full range of commercial 2 3/4 and 3 inch shells.  Combining proprietary engineering and renowned Turkish craftsmanship, the new SE122 Tactical may be the most reliable and versatile semi-auto we have ever produced.   Served up with (1) 5+1 and (1) 2+1 round magazines and a hard plastic carry case!
