The barrel has a longitudinal passage extending through the barrel and a lateral passage extending through the barrel and intersecting the longitudinal passage. A second open end of the barrel is configured to engage a rod receiving head to which one of the locking caps is threadingly connectable. The magazine has a housing with a chamber for receiving a plate carrying a plurality of locking caps. The chamber of the housing is aligned with the lateral passage of the barrel so that the plate is movable from the chamber into the lateral passage so that one of the locking caps is positioned in the longitudinal passage so as to be matingly engageable with a drive tool insertable through the longitudinal passage.
