The SU-22 functions through blowback action with a 4140 steel bolt moving along steel guide rails within the polymer receiver. An ejector is linked to one of the guide rails, and the recoil spring sits above the barrel. It features an adjustable rear sight for windage and a front sight for elevation. Additionally, it includes an integrated Picatinny rail on top to accommodate various sighting accessories. The barrel\'s muzzle end is threaded 1/2\"-28, able to attach standard additions like a muzzle brake. Moreover, it comes with a 26-round semi-transparent magazine.
