A graft formation and delivery instrument comprising an outer barrel, a piston, and an inner pin. The outer barrel has a center aperture. The piston is seated within the center aperture, has a through bore, and is operable to move within the center aperture. The inner pin is seated within the through bore of the piston and operable to move within the through bore. The outer barrel receives multiple graft components that are contacted by at least one of the piston and the inner pin to assemble a composite graft from the graft components. The instrument is operable to direct the composite graft to a desired implant area and deposit the composite graft at the implant area.
