It is, at best, unclear what impact Obama's dictum will have on private sellers. Apparently, if you are in the "business" of selling firearms, you have to have a FFL. What he means by "business" is problematic--selling two or more guns at a gunshow, or to a dealer?? So far, I see nothing that says you need a license to sell me your gun, or that you have to run a background check on me before you do.
This is Obama, grandstanding to build his "legacy," with another vague, dictatorial Executive Order that'll probably be challenged in the courts:
