Abstract

Structure is provided to circumferentially and longitudinally position a charge tube within a carrier tube, so that the charge tube charges are align ed with the carrier tube scallops. A top collar, having an external key, is secured to the top of the charge tube. A vertical groove is machined through the top threads of the carrier tube. When the key enters the groove the carrier tube is circumferentially oriented. An externally threaded steel disc is screwed int o the internal bottom threads of the carrier tube, to longitudinally position the charge tube when it is inserted into the carrier tube and abuts the disc. Th e disc further functions to support and retain the charged tube in the carrier tube when a gun section is in an upstanding position without a bottom tandem plug in place to perform these functions.
