Nice looking Yugoslav SKS 7.62x39 with two mags. One metal mag, one poly mag. 
This SKS has the grenade launch feature. Has a bracket to mount a bayonet (bayonet not included). 
It features a semi auto or single shot firing mechanism. Single shot is typically used to fire a blank launching the grenade. 
The rifle is stuck in single shot mode. It appears to me the gas port is dirty. I can't remove that portion of the rifle to clean it. 
I have fired the rifle, shoots accurately. In very nice condition.
