A modular cleaning, display, and storage rack for firearms is disclosed for holding or displaying one or more pistols. The firearms rack can hold one or more pistols for cleaning and/or displaying. The firearms rack can also be folded flat for easy storage and/or transport. Multiple racks can be nested or stacked together and occupy less space than a single rack. The rack includes a base, and a plurality of support rods disposed in a spaced apart relation and hingedly operable relative to the base. In an open condition, the plurality of support rods are angularly disposed above the top surface of the base. The firearm is supported on the support rod by insertion of the support rod into the barrel of the firearm. In a closed position, the plurality of support rods are oriented such that they are substantially aligned with the back surface of the base.
