Event organizer "2nd Enforcers" had said it was expecting more than 2,000 at the Saturday event.
Most of those present were armed with long guns slung over shoulders or holstered handguns. Many carried signs critical of President Barack Obama and defending gun ownership. One held aloft an upside-down American flag.
Rally attendees cheered speeches telling of a "progressive conspiracy," warning against allowing children to become "slaves of the government" and citing Nazi Germany and contemporary Australia as cautionary tales of a disarmed citizenry.
Multiple speakers encouraged those assembled to keep posting pro-gun sentiments on Facebook even if people unfriend them.
The rally anticipates a House vote on requiring background checks on all gun purchases in the state.
