They do offer a straight-line stock like the Dragunov that requires a cheek pad. The PSL stock is designed, at least in theory, to not require a cheek pad. The design is purposeful and for a bunch of folks works fine.
I actually find the PSL stock better overall than the SVD for two reasons: better grip and shock-absorbing butt-plate. The PSL I have has a thinner grip than the SVD I have (no, not Tigr). The butt plate on the PSL is spring-loaded which helps tame recoil and that is nice. The SVD cheek pad is more comfortable than the PSL's curved wood, but in all other ways I find the PSL more comfortable.
Mis-labeling the PSL as a Dragunov can be irritating, but it doesn't really bother me anymore. There is far too much info on the internet that is far too easy to acquire for anyone to claim ignorance when making a purchase. That is just plain stupid on an auction site when you can type in "Dragunov" on Google in a separate tab and get all the info you need. Someone who doesn't have a computer but buys one from a catalogue might have some room to gripe, but even then, if they don't mind shelling out that kind of cash without researching the product they should not mind getting something that is not an SVD. If they are upset, they can sell their rifle for what they paid for it.
