The whole mount is QD. You need to buy the Dragunov/POSP side plate separately.
A WHOLE lot more expensive way to go, but the POSP side plate is a slick, modular system all its own, that allows you to mount any of the standard East Block style side mount systems. If you want to play around, its an option. If you look under "accessories" ar Corwin Arms, you can see a few different mount options. If you look under "optics" you'll find a range of well made scope/side-mount combos for some very good prices. If you buy the side-plate, then go with a mount/scope combo, you can put some ridiculously good optics on it for a lower overall cost.
