But calling an AR-15 a "military assault rifle" is probably enough evidence that you don't know what you're talking about, anyways. ('Assault Rifle' is a term of art and the vast vast majority of AR-15s do not qualify - the legal ones that do qualify have literally never been used in violent crimes in the US, because they are worth tens of thousands of dollars and machine guns (a superset of assault rifles) have had universal background checks since the 1920s)
