Some of the people freely and legally carried guns at the rally. Others held pro-Second Amendment signs.
Open-carry advocates and other organizers oppose a proposed federal assault-weapons ban, though that provision was pulled by Democrats from gun-control legislation on Wednesday. While the Republican-led Legislature is unlikely to pass any gun-control bills, gun rights groups say they want to keep hammering home their opposition in Lansing.
Some Democrats have proposed ending the ability of concealed weapons permit holders to openly carry guns in Michigan schools. It's currently legal to openly carry in gun-free zones but not to conceal a weapon.
The Capitol Facilities director estimates 400 to 500 people participated in the rally.
