Received my upper last night. The gas tube is not quite center, but took the bolt out of my carrier and slid my carrier into the receiver, seems to mate with the gas tube just fine.
The low pro gas block however, is not centered in the free float rail. It is actually making contact with and sitting up against the rail on the right hand side (when looking down the barrel.) Pictures aren't great but just to give you an idea. Would this be an issue? Free float is supposed to be free floating lol. Thank you,

This is the third upper i have purchased from PSA in the last month, and will be the third sent back to them. The first had a receiver that was marred very badly, the second was the same. This one is as well, along with the rail being marred and dinged up and the gas block not installed properly. I am sick of receiving items that appear to be used, and poorly put together. All three items should not have left PSA in the condition they were in. I like your products, but quality control is disappointing. The hassle of having to send things back and forth and continue to bug CS is unnecessary. I hope this can be made right, or I will not be doing business with PSA anymore. Shame, being i love the uppers, if only they were sent in new condition and properly put together. (As advertised) |

Also placed reviews on their website regarding the first two purchases, describing my issues, and the reviews are nowhere to be seen. Seem to be censoring their reviews. |

I'm glad you posted your description and pictures of this problem. I ordered and received over the Memorial Day holiday the 16" CHF Mid-length ULW 13" Keymod upper. I noticed it has the exact same issue as you describe. I have this evening sent an e-mail to PSA customer service regarding this and informed them that I learned about the problem from your post on this site. Hope to hear from them soon.
I have ordered a number of items from PSA and have always been totally satisfied. With the exception of the off center gas tube/gas block, this upper was flawless in fit and finish. I'm hoping that PSA will be able to realign the gas block and send this upper back to me. Thanks again for your post. |

UPDATE
The first upper i ordered, (not the one pictured above) arrived tonight. I had sent it back to PSA because of a badly marred upper receiver. It looks great! ... So i am giving it a once over, and slide my CH and BCG into the upper receiver and... clank. The BCG will not mate with the gas tube unless it is given force. Took the bolt out and slid the carrier in to confirm. Sure enough the gas tube is off. To double check i grabbed my other BCG and performed the same test. Yielded the same results. The carrier will not mate without a good amount of force, and will not slide back out of the upper receiver without force. Both PSA premium BCG's by the way, and both mate with my other upper (the one pictured above) beautifully (yes the one with the gas block sitting against the rail). I do not know what to do lol. Now will have to send this upper back for the second time, along with my railed upper pictured above. Though this will only be the first time sending the railed upper back LOL. I just want to shoot damnit.  Please PSA help me out. I am getting verrrry irritated with all of this. By the way, I ordered the first upper on May 10th. I am trying to be very patient. 3 uppers, one will now be sent back twice for repair, the second sent back for a refund due to damage, and now the third (pictured above) will be sent back as well. All the while, CS does not seem to care. A simple I'm sorry would do wonders, maybe expedited shipping, or "I will personally make sure you receive a new, working upper this time around" Something besides "sent you a shipping label go ahead and send it back".
Anyways... ONE more chance will be given (on both uppers) after that I will be returning both and purchasing one BCM upper for the same amount that i paid for both of PSA's, Rather have one rifle that works, than two that don't at this point. |
| Sorry to hear that you still have issues with the replacement. I think it's really a hit or miss regarding PSA uppers. One of my friends bought the same ULW upper the other day. I sent the link to this post to him and he checked his upper and told me he didn't have any issue presented in this post. |

You hit it on the head. Unfortunately it is the luck of the draw. As said previously, if these uppers came in good condition, and properly put together, I would be stoked with them. Quality control and Customer service are my only issues with PSA. Unfortunately those are significant factors to a good company. It seems that they put out such a high volume, that they send some items out that should not be passed by quality control, and they are okay with that. Some of the bad apples go to customers who do not care, or do not know any better when it comes to a quality product, or even fix little things like my two issues, the gas block on one, and the gas tube on the other... not knowing that they void their warranty in doing so. |
| I just hope that they will allow me to return for a refund if they come back unusable the next time. By the time i receive one of the two back (for the third time) it will be outside of the 30 day return policy. Even though i have only had the upper in my hand for a total of 2 business days during the 30 days LOL. |

I sent an upper back for a warranty issue after I had had the upper for over 6 months and PSA had no problem with it. Maybe since I wasn't asking for a refund it was different. |

Even though you should not have to ''fix'' things on a new upper it seems silly to send it back over something so easy to address. You do realize you can simply push the end of the gas tube over a bit. You can use a finger or a screwdriver and be shooting in 30 seconds. Even rotating the gas block on the other upper would have taken less time to do than packaging it up to ship back? Even if you had to loosen the rail to get to the gas block screws it would be a 10 minute fix. If you can reach the gas block screws from under the rail it would take less than a minute and your shooting. I don't want to sound like a jerk but you should really try to become familiar with the AR so small issues do not require shipping the gun off to fix. |

While I am new to the AR platform, i have learned a lot about it recently, When i get interested in something i research the shit out of it. I am confident that i could fix these issues. ( I went the 80% route, and was able to assemble my lowers including milling.) I had the time and money to be able to do so. With that being said, there are three reasons why i do not. 1) Principle. I should not have to. 2) I do not have the ability to purchase more needed tools to tinker with the upper components. That's why i purchased complete uppers. Although as you state, it may only take simple tools that i already have. I have not looked into what it would take and what i would need, because of reason 1. 3) I was told that doing anything of the sort would void my warranty. Even though PSA may not be able to tell that i made simple corrections such as these, that is not a chance I am willing to take. The warranty is there for a reason. You do not sound like a jerk. I understand where you are coming from. Thats why i said i hate bugging CS with shit like this. BUT, when i purchase something new and ready out of the box, i expect it to come that way. Especially when they are things that are so tedious, like putting new, unworn components on the assembly, and making sure everything is straight and correct. They have the tools and know how to make and sell these complete uppers, that is what i paid them for. That is what i expect. Lastly, I am not in dire need to shoot ASAP, so for the reasons above, I will go the proper, albeit pain in the ass route, to make sure PSA does their part, and i get what i paid for. |

It's just easier to assemble or fix them yourself once your comfortable dong it. |

I posted earlier that my recently received PSA 16" Mid-length, CHF 13" ULW upper had the exact same issue listed by the OP. I talked with Claudia at PSA CS who immediately issued a return label. She was very polite and helpful. Thank you Claudia!
I am a long time firearms owner but only recently became interested in the AR-15 so my knowledge is very limited as are my gunsmith skills. My concern about not attempting any repairs or adjustments on my own are the same as the ones listed by the OP above. I have some additional concerns as well that may simply be due to my ignorance of how the gas system works. 1. If I understand the gas system correctly (and PLEASE correct me if I'm wrong) there is a gas port hole in the top of the barrel that bleeds gas into a corresponding hole in the gas block that is directly above the hole in the barrel, right? To me, if the gas block is misaligned, wouldn't that mean the the two holes are not directly above one another? If so, it does make sense that simply adjusting the gas block would solve the problem. But couldn't it also be that the gas block is NOT misaligned, and it's just because the entire barrel needs to be turned slightly in the other direction to properly center the gas block in the handguard? If this was so, then moving the gas block ONLY would then misalign the two gas holes resulting in an impaired gas system. Or do I just totally not understand this? 2. I would really hesitate to try and remove the free floating handguard as I have no instructions as to how it's actually attached other that seeing the exposed screws and have no tools for the barrel nut etc. I'll apologize in advance if my ignorance on this subject is just wasting everyone's time! |

Thank you for your comments, and we apologize for the inconvenience.
To address your concerns: 1. By design, the port in the gas block is much larger than the port in the barrel. The gas block would have to be quite a bit more angled before function is affected. All of the uppers have been test fired to check function before shipping. The issue described is mostly cosmetic, and has to do more with the rail being truly free float if there is something touching it (which is true). We have sourced the issue to a particular batch and it has been addressed in production. The gas port in the barrel is located and drilled after the barrel extension and locating pin have been installed. The locating pin fits into a slot on the receiver at TDC - the gas port is on that same alignment. 2. We always recommend that you allow us to take care of these issues for you. However, the hand guard on this particular upper is easy to remove with simple tools and should not be difficult to re-install correctly. Loosen the three bottom allen head "pinch" bolts, then tighten the small allen head screw on the same side - this will loosen the rail on the barrel nut. To remove the rail, remove the allen screw on the opposite side, and carefully slide the rail off. Installation is the reverse. Be sure to loosen the small allen screw on the same side as the pinch bolts before tightening the pinch bolts - that one can keep the pinch bolts from fully seating. The pinch bolts only need to be snug - no need to over torque them. As with working on you own car, if you take it apart, you will affect the warranty. This is why we offer to do it for you. If, however, you are mechanically inclined and are adept at tools, it should be easy enough. |
