While based on the 5.56-chambered SU-16, the SU-22 is not a simple conversion kit, but a standalone firearm chambered for the .22 LR and designed for target shooting, plinking, or small game hunting. The SU-22 operates by blowback action and has a 4140 steel bolt that rides on steel guide rails inside the polymer receiver. The ejector is attached to one of the guide rails and the recoil spring is located above the barrel. The cross-bolt safety and magazine release operate identically to the SU-16 and it will accept many of the same accessories including the slings, stocks, and compact forend. The rear sight is adjustable for windage and the front sight is adjustable for elevation. An integrated picatinny rail on top will accept a multitude of sighting options. This rifle features a shrouded blade front sight, an adjustable ghost ring rear sight, and a cross-bolt safety and comes with the original factory box. Its stock, metal, and bore are all in very good condition.
