I see, and agree that is poor. My HW100 was an early one from 2006 and I'm sure it didn't have that rib. That it was deemed necessary suggest bad stock inletting again, so it would IMHO have been better to address that aspect.
The GinB stock I had was made with hand tools on the other side of the world than the action that was to sit in it, and it still was a perfect interference fit. So it can be done.
As soon as the action was in that stock the barrel band became an irrelevance. I threw it to the bottom of the bits box and it lies there still... 10 months after I sold the gun!
Free floating barrels are the way to go.
