Bolt carriers and bolt heads in the very early guns were Swiss. I suspect hammers were too, as they had the exact same markings as Swiss hammers. The very very earliest 556 rifles looked to me to use Swiss gas pistons as well, though they were blued steel vs stainless steel as was used on Swiss 551 by that time.
