If sent to me I would put it through as a remington warranty repair
Finally. Remington used to do thus repair for free including sending a box and a shipping label. Maybe still do, There is nothing weong with a proper braze job unless all the books are lieing about strength. Or you wail on it with a 5 pound sledge. Tes, Remington did have a process control problem but that happens across industry.
Or have it TIGed and wonder if your guy made a cold weld. X=ray to be sure?
