Ted Cruz

Has always supported the right of the American people to own AR-15s and similar firearms.

Donald Trump 

Favored banning these and similar firearms into the 2000s. Now claims to be very pro-Second Amendment.

John Kasich 

...voted for the 1994 Assault Weapons Ban as a member of the House of Representatives, which banned this and similar firearms. Says he is now not longer in favor of such bans.
