...something like that.
That's correct. And applicable to MO as well.
But that said... there are still laws on individuals selling to other individuals who can't legally own...
It is unlawful to knowingly sell, lease, loan, give away or deliver a firearm or ammunition to any person who is not lawfully entitled to possess one. It is unlawful to recklessly sell, lease, loan, give away or deliver a firearm or ammunition to a person who is intoxicated.
It is unlawful to knowingly sell, lease, loan, give away or deliver any firearm to a person who is not eighteen years old without the consent of the custodial parent or guardian.
That's applicable without FFL. Although very hard to enforce.
