The dragunov shares one or two design features with the AK, but is really it's own design. Actually, the Dragunov shares at least as many design features with the SKS.
There are a few SKSs out there with side mounted scope rails above the stock and their own corresponding mounts, but they are quite expensive and if not already installed, its installation would determine whether or not it shoots well at all.
For the money, a scout type mount that replaces the rear site would probably be a good way to get the best accuracy out of the SKS.
