It's great, but I don't believe they have found a replacement for the noveske barrels which haven't been available for some time. They were asking people what they would want for a replacement so i think it will be awhile before they are available again.
I'm having one built right now on a non-Noveske barrel. It's an additional charge for machining time so the contours all match up, but when you factor in the astronomical price of the noveske barrel, I'm still coming out ahead even with the additional mâché time.
