The shop is incredibly helpful and offered to either weld the port and redrill or replace with a new Colt barrel (in another email). I don’t want them to have to source a new barrel if the weld method is equally or even stronger than a factory gas port. But I’m unsure how durable it would be and if would erode quicker or be a weak point. Has anyone ever heard of this technique or is familiar with welds on a gas port? Here is there explanation below...
What barrel length did you have it cut to?
