A guy on the SKS forums bought one for the SKS. To me they look like they were made from kitchen cutting boards. His review was not very favorable for a $350 stock. He said it looked like a very early beta stock. There are unfinished cut edges all over, there were gaps and non flush mating of surfaces, overall the quality fit and finish resembled a prototype not a finished stock.
the magazine release tab can easily be reached if you want to run detachable duckbills (outside of California of course)

Also there is a foldaway front pistol grip

Now the real problem.
The stocks fit and finish scream "ALPHA PROTOTYPE"
Its neat how its all put together but there are rough sawn edges, panels not quite matching up etc.
This stock would be a killer if they went the injection molding route.
Maybe this will come in the future, but for 350 bucks as it is right now, they are not quite there, I really hope the "pro" this up a bit more.
