So I ordered the stock and it came in today.
Just installed it and it's a completely different feeling gun. It shoulders quickly with the reduced (12.5") LOP. This stock came with the LimbSaver recoil pad and it looks and feels like it should work well. I hope so because the SuperNova stock handled recoil like a dream.
Playing hooky tomorrow to go out to the desert to shoot.
I'll report back in another 3 years.
