Scott,
same here.
My solution is a far from being as solid as yours but very simple. From the DIY market I have self adhesive aluminum tape 0.05mm (0.002") thick and 2" wide. From the depth of the groove I know the number of stripes needed to be cut from the tape. After applying them to the barrel it works pretty much like without groove.
