This is the monolithic one piece upper from Mega, so it uses a proprietary barrel nut. That nut needs a specific tool to be installed since the rails are not removable. That's the long tubular piece in the lower right side of foam, then the small circle in foam is where the barrel but is located. This set also comes with the charge handle and ejection port door.
