The curvature is modeled after my Mauser model 98. The overall design is IMO quite elegant but more importantly, it is VERY comfortable to hold and shoot.
The following definitions apply to terms used in the identification of assault weapons pursuant to Penal Code section 12276.1:
(d) "pistol grip that protrudes conspicuously beneath the action of the weapon" means a grip that allows for a pistol style grasp in which the web of the trigger hand (between the thumb and index finger) can be placed below the top exposed portion of the trigger while firing.
By that definition, your "fixed stock" would still be considered a pistol grip. When grasping your "fixed stock" you can still use a pistol style grasp where the web of the trigger hand is below the action - all that white space below the pink line in the image you quoted.
That is why the U15 stock goes straight back from the receiver rather than curving down like yours.
