Abstract: A technique facilitates perforating operations. According to an embodiment, a perforating gun system utilizes a plurality of modular perforating gun sections which are readily assembled to create a perforating gun with a desired number and orientation of shaped charge holders. In some applications, the modular perforating gun sections may be formed of plastic, e.g. injection moldable plastic, to further reduce costs and provide great flexibility with respect to construction of the desired perforating gun.
