A relay connector for joining together two lengths of flat printed circuitry or flat flexible cable is formed from two connector housings of identical shape. In use, creation of a defect ticket is initiated for an identified defect for submission to a defect tracking system, the identified defect being identified during a software development life cycle. Each liner is insertable through a rear opening of an upper receiver portion of the rifle and into a smooth bore barrel of a modified barrel assembly. The system may include a handle extension configured to radially rotate substantially one hundred eighty degrees in a first direction on a single plane to extend the push arm and the guide arm. The memory is accessible to the processor and stores a key for authorizing use of the software tool.
