I’m aware of several solutions for mating a colt large hole lower to modern small hole uppers ( Fulton armory has a good one) but I am not aware of any solutions to do small hole lower to large hole upper. At least until post above! Lol
There are offset adapter things but after seeing how these things don't work I would never want them in a rifle that I would trust my life with. I'd repair the upper or lower and move on with life without that stupid f****** adapter in place.
