I don't know anything about these dudes but apparently they are gearing up to make a bunch of US made parts. The barrels and trunnions interest me the most. I have no idea about the quality. He is also selling an 80% receiver, but unfortunately he is trying to reinvent the wheel by making them with an oversize wall thickness. At least the extra thickness is on the outside rather than inside, so shaving trunnions is not required. There would of course be fitment issues with the top cover, selector, axis pins etc. It will be interesting to see where this goes.
