There wouldn't be any disadvantage to welding it in place though would there? I do currently have another tap, Drilled the hole with a 7/64th like I was supposed to, used plenty of oil but the tap would not bite, once it did it snapped. Shouldn't be as much of a pain in the ass as it has been, I know it's an easy task. What really sucks is that one easy task is messing with the overall functionality of my weapon.
