I wouldn't mess with it.
This is what my Sub MOA S2 does with factory "Zombiemax" ammo. I let it cool completely between shots. Admittedly that's a three shot group versus five (ammo prices prevent 5 shot groups right now). I would not change the stock for anything. That group measures .35 and was shot from sandbags.
