It could be a chinese SKS-M paratrooper, thought the original pic at the fox article is not. The SKS-M is the only SKS designed to use detachable magazines. It is rare.
I should have bought one when I had the chance, but 400 bucks for an SKS made me balk
I would like to see the adapters that were used to make the sks receiver accept the mag. Probably where the aftermarket(?) adapters were designed from. The original sks receiver has to be remilled and resized to accept the ak mag without adapters. The stock mag tabs fit between the stock and the reciver, with the raised groove at the back of the mag fit into the groove in front of the trigger guard. If they wanted to do that, why not just issue the AK to the paratroopers? It is shorter, more rounds etc, the true "assault" weapon, in full auto mode.
Regardless, that model sure is pretty.
