Carpmaster, when I got mine back, I could tell a huge difference in every way the action operates. They basically polish and hone everything about the action, making it much easier to break down and the trigger was 1 1/2lbs lighter and it broke more crisp and clean. With my 308 pistol barrel at 100yds, I gained 3/4 of an inch in my groups!! So, like I said, it was definatley worth it.
