ABSTRACT OF THE DISCLOSURE A barrel assembly for attachment to a standard driving tool has a barrel bore to accomodate fasteners positioned in it for driving. A carriage assembly is positioned within the end of the barrel so as to form an internal restrictive bore for the fastener in a first position and an enlarged bore in a second position so as to permit the fastener to pass therethrough. The carriage assembly includes a sleeve slidable in the barrel bore and having spaced through slots. Fingers are pivotally mounted in the slots and extend into the bore to center and hold a fastener. The sleeve is movable from a position where the fingers are held against pivoting by engagement with the barrel bore and a position where the fingers are aligned with openings through the barrel wall to permit their pivotal movement for the release of fasteners.
