I would far prefer they offer a threaded barrel that is identical in length to the crown as that of the 16" OAL 551 barrel, then offer US made flash hiders that are the same spec as that of the 16" OAL 551 barrel. The flash hider could then be added, blind pinned/welded to make a 16" OAL barrel and a title-1 rifle with the requisite US parts.
