The rules have changes and I want to potentially use my MR556s. I tried searching but didnt find any gunsmiths that do match grade uppers. I found Rocke but from what incould tell they have rifles and dont do build them selves.
My current rifles are LMT lowers with a Geissele trigger and White Oak Precision uppers. Its a tried and true combination. Is anyone aware of a gunsmith who does this kind of work? Krieger will make the 20" barrel but I do need to get it set up in my upper. Any help or direction would be greatly appreciated.
