I recently installed one of these stock sets on a customer's WASR-10/63 and I was very surprised by the quality of the thing.
It was a very solid, tight-fitting stock set that looks pretty sharp.
The handguards were a total bitch to fit, about an hour with the dremel and file. But it turned out good.
The buttstock fit in very easily.
The pistol grip had deep finger grooves and was very comfortable.
My only complaint was that the adjustable cheek piece made it very difficult to see the iron sights. So i left it off.
I really like how the set came with the option of installing railed or flush-fit pieces on the handguards (which was convenient because the sling mount on the handguard retainer was obstructed by the rail).
So long story short, a great stock set for the money.
