Not having seen actual pics yet, but knowing that optics and AKs are like competency and democrats, the rifle is probably a Dragunov.
Hard to identify based off one fuzzy picture so far, but here goes.
To me the rifle appears to be a modified SKS type - converted to hold a 30 round magazine. They are relatively cheap and pretty common.

(this one has a 20 round mag)
Not an AK - AKs by and large have a prominent pistol grip, as well as a large distinctively shaped magazine.

AK type
I don't think that it's an SVD (Dragunov) or PSL rifle. 1) They are somewhat unusual and pricey, 2) they are pretty large - about 45-48 inches long, and 3) they both have a 10 round magazine.

SVD

PSL
As a side note, a guy named Francisco Martin Duran used the same setup (SKS with extended magazine) to shoot up the White house in 1994. https://en.wikipedia.org/wiki/Francisco_Martin_Duran.
