Removing the gel was the first thing I did to my pro hunter .308 when I got it home last year. I used a large flat bladed kitchen knife and a little rubbing alcohol poured in to help lubricate the cavity as the blade was removed. I pushed it down both sides of the stock and the gel popped right out. I then filled the void with wal-mart bags and put the recoil pad back on. I personally think Kimber puts the gel in just to make the gun heavier so they can steer buyers who want a really light weight gun towards their Adirondack. It no doubt has a nicer stock but once the gel is removed from the hunter the weights are nearly identical. I think there are more than a few guys who would save several hundred bucks if they knew they could just buy the hunter and remove the gel and get essentially the same rifle.
