The SR-3 Vikhr is mechanically based on the AS-VAL and VSS Vintorez rifles, but built to be a very compact personal defensive weapon instead of a silenced rifle. Still chambered for 9×39, the Vikhr is intended for roles like executive protection, where the priority is being compact and concealable. With elements like a top-folding minimalist stock and vz.61 Skorpion-like charging handle, the original model of SR-3 Vikhr fits this role pretty well. The later SR-3M model moved to a more traditional side-folding stock and regular charging handle.
