An apparatus comprising a charge tube for a perforating gun assembly used in harvesting energy in a wellbore and a retaining projection formed on an end of the charge tube. When the charge tube is inserted into a gun body, the retaining projection engages with the gun body of the perforating gun assembly to restrict movement of the charge tube with respect to the gun body when engaged with the gun body. The retaining projection can comprise a plurality of collet fingers on an end of the charge tube that engage with the gun body to longitudinally retain the charge tube. The retaining projection can comprise at least one alignment finger that limits radial movement of the charge tube with respect to the gun body. The retaining projection can comprise a plurality of centralizing bend tabs that restrict radial movement of the charge tube when inserted into the gun body.

1. An apparatus comprising: a charge tube able to be inserted into a gun body of a perforating gun assembly for use in a wellbore, the charge tube having a retaining projection integrally formed on an end of the charge tube,wherein when the charge tube is inserted into the gun body, the retaining projection engages with the gun body of the perforating gun assembly to restrict longitudinal movement of the charge tube with respect to the gun body when engaged with the gun body. 2. The apparatus of claim 1 wherein the retaining projection is integrally formed by at least one of: cutting, machining, molding, casting, forming, welding, and sintering the end of the charge tube. 3. The apparatus of claim 1 wherein the retaining projection comprises at least one alignment finger located at an end of the charge tube and that limits radial movement of the charge tube with respect to the gun body when engaged with the gun body. 4. The apparatus of claim 3 wherein at least one alignment finger is engaged in at least one slot on an inner surface of the gun body. 5. The apparatus of claim 1 further comprising a plurality of charges supported within the charge tube. 6. An apparatus comprising: a charge tube able to be inserted into a gun body of a perforating gun assembly for use in a wellbore;a retaining projection formed on an end of the charge tube that, when the charge tube is inserted into the gun body, engages with the gun body of the perforating gun assembly to restrict movement of the charge tube with respect to the gun body when engaged with the gun body,wherein the retaining projection comprises a plurality of collet fingers formed on the end of the charge tube that engages with the gun body thereby retaining the charge tube within the gun body. 7. The apparatus of claim 6 wherein the collet fingers engage a groove on an interior surface of the gun body. 8. The apparatus of claim 6 wherein the collet fingers are cut and formed into collet fingers on the charge tube. 9. An apparatus comprising: a charge tube able to be inserted into a gun body of a perforating gun assembly for use in a wellbore;a retaining projection formed on an end of the charge tube that, when the charge tube is inserted into the gun body, engages with the gun body of the perforating gun assembly to restrict movement of the charge tube with respect to the gun body when engaged with the gun body,wherein the retaining projection comprises a plurality of collet fingers that engage with a groove formed on an interior surface of the gun body and the retaining projection further comprises an alignment finger that radially engages with a slot on the interior surface of the gun body. 10. A perforating gun assembly for use in a wellbore comprising: a perforating gun body; anda charge tube disposed within the perforating gun body, the charge tube having a retaining projection integrally formed on an end of the charge tube,wherein when the charge tube is inserted into the gun body, engages with the gun body of the perforating gun assembly to restrict longitudinal movement of the charge tube when engaged with the gun body. 11. The perforating gun assembly of claim 10 wherein the retaining projection is formed by at least one of: cutting, machining, molding, casting, welding, forming, or sintering the charge tube. 12. The perforating gun assembly of claim 10 further comprising a plurality of charges supported within the charge tube. 13. The perforating gun assembly of claim 10 wherein the retaining projection comprises at least one alignment finger formed on the end of the charge tube that limits radial movement of the charge tube with respect to the gun body when engaged with the gun body. 14. The perforating gun assembly of claim 10 wherein the retaining projection comprises a plurality of centralizing bend tabs formed on the charge tube to restrict radial movement of the charge tube when inserted in the gun body. 15. A perforating gun assembly for use in a wellbore comprising; a perforating gun body;a charge tube disposed within the perforating gun body; anda retaining projection formed on an end of the charge tube that, when the charge tube is inserted into the gun body, engages with the gun body of the perforating gun assembly to restrict movement of the charge tube when engaged with the gun body,wherein the retaining projection comprises a plurality of collet fingers formed on the end of the charge tube that engage a groove on an inner surface of the gun body, the plurality of collet fingers configured to retain the charge tube within the gun body. 16. An apparatus comprising: a charge tube able to be inserted into a gun body of a perforating gun assembly for use in a wellbore, the charge tube having a plurality of centralizing bend tabs extending from an end of the charge tube,wherein the plurality of centralizing bend tabs are formed by deforming the end of the charge tube,wherein the plurality of centralizing bend tabs restrict radial movement of the charge tube when inserted in the gun body. 17. The apparatus of claim 16 wherein the plurality of centralizing bend tabs engage an inner surface of the gun body to restrict radial movement of the charge tube with respect to the gun body.
