Actually, I do believe that is the AS-Val, an extremely similar weapon.
The two share a lot of parts commonality, and can even take each-other's magazines.
The AS-Val has the same skeletal style buttstock as depicted on the models here, and uses 20 round mags as standard. It is often encountered without a scope. It is designed first as a silent assault rifle. It's cousin the VSS is designed with a sniper roll in mind. It has a 10 round mag to make firing from prone easier, and has a Dragunov style buttstock, and is always issued with a scope.
