The Rock Island Arsenal Museum
in Rock Island, Illinois right across the Mississippi from Davenport, Iowa. This is right on Interstate 80 and if you are much interested in the historical side of firearms you should know about this little-known(in my opinion) museum. Go drive around the arsenal compound....the limestone buildings are neat and there is a confederate cemetery there.(It was a Civil War POW compound.) Then go into the museum which is 100% rifles, handguns, and a bit of artillery. There are rifles there the Native Americans used at the Battle of the Little Big Horn. If you are in the area take time to do this. There are many, many rifles. Well displayed.
