The invention is a stacked tube component feeder with changeable parts to accommodate different size components. A feed station, including a channel, is mounted on a base. The feed station includes a slot for holding component tubes. A changeable component track is mounted in the channel, and a singulator is mounted on the component track to prevent the feeding of more than one component at a time to a changeable component nest. A removable nest is mounted on the base for receiving components from the removable component track, and transports the component between first and second positions on the base.
