Zusammenfassung:	A perforating gun system may include a gun body and a charge tube disposed within and rotatably mounted to the gun body, wherein the charge tube includes a receiving feature disposed at an axial end of the charge tube. The perforating gun system may also include at least one charge mounted within the charge tube. The at least one charge is configured to perforate a sidewall of a wellbore upon detonation. Additionally, perforating gun system may include a weighted feature adjustably attached to the receiving feature of the charge tube in one of a plurality of angular positions, wherein adjusting the angular position of the weighted feature is configured to adjust a center of gravity of the charge tube such that gravity will cause the charge tube to rotate to a corresponding phasing angle.
