A modular quiver system and method of use may include, first, a base portion configured to be attachable to a bow and configured to removably hold a first arrow, and second, a detachable portion configured to removably hold a plurality of second arrows and configured to be removably attachable with the base portion by hand without the use of any tools, regardless whether or not the base portion is attached to the bow, and regardless whether arrows are in the quiver. A quick-release bracket system allows the modular quiver system to be removed from and attached with a bow in different predetermined positions without the use of any tools.
