Mine has developed a split where the inner tube locks into place
I contacted Henry and they offered to send the parts to Viking Arms for repair under warranty.
Viking have been in touch and say it will require a new barrel, outer mag tube, inner mag tube, gunsmithing and re-proofing of the rifle and it will cost me!.
I can't see how the mag tube would be connected to the barrel?, surely it's fitted into the main receiver/frame of the action?.
Photo attached showing the splits, I may see if I can just get it welded or even epoxied.
