Billet construction provides greater material integrity than forged receivers, especially around critical stress points like the buffer tower. This is essential for a straight-blowback 9mm AR platform. As an unfinished receiver, it is not a firearm under federal law, but final assembly must comply with all ATF regulations, including those for pistols and rifles.
