Quoted: I am wondering if this is based on the assembly tool. I found this exact issue to be a real problem with my own builds, concerning torquing to spec, or slightly over spec, using a Geissele reaction rod. The design is such that while the reaction rod holds the barrel at the extension, the upper receiver is free to rotate and press against the barrel pin under torque. The upper being aluminum against a steel pin, torquing can cause an indentation of the upper receiver at the threads. If I was not careful, my pinned front sight block was canted. I stopped using the reaction rod and switched to the Midwest Industries Upper Receiver Rod. This tool has a top bar which runs the length of the rod, so the full run of the inside of the upper receiver at the charging handle groove. It does not allow the upper receiver to rotate freely under torque, thus not allowing the barrel pin to indent or damage the aluminum threads of the upper reciever. Quoted: Quoted: If you commit to this, please please do something about QC in your barrel department. Its becoming common theme on Facebook and the interwebs to see a psa fsb barrel with either the fsb canted left (from behind), or the feed ramps misaligned (counter clockwise). If you guys could step up qc you'd be a great thing for the community with your pricing. I am wondering if this is based on the assembly tool.

SOTAR recommends against the reaction rod for this exact reason. |

I know its not popular to take up for big companies... I don't see the connection between making retro lowers and some QC issues with barrels made under their Value Brand. If you had some issues with their lowers that would make sense. Being an industry price leader comes with its own set of challenges, from what I see they handle those challenges well. They will fix ANY issue that someone has... even pay shipping both ways. Since they do fix their issues when they pop up, I bet they are aware of problems. You will not see the correct ratio of success to failure stories on the internet. When you are running the numbers of parts at those low margins there will be QC issues. If they fix the issues as they pop up then what is left to gripe about? |

The production of ten thousand plus lowers per week is hard to fathom. I can’t imagine the amount of machine oil or milling bits they burn through daily (or the size of those “chip” bins). PSA taking care of customers was the exact reason I’ve had such a great experience getting to know some of the folks there. Not sure the responses or the post requesting attention to detail was a gripe, observation maybe. Most of us following this thread are very excited to see what PSA comes up with. I will agree their CS would be hard to beat. |

Quoted: This is excellent news! I’m looking forward to these lower receivers, and I’m sure that many others are as well. I hope that these will be great sellers for Palmetto State Armory. Quoted: Quoted: I am sure they will be non-reinforced as we are looking to do the as closely as possible. Thank you, Josiah This is excellent news! I’m looking forward to these lower receivers, and I’m sure that many others are as well. I hope that these will be great sellers for Palmetto State Armory. I've been hoping that PSA would offer these lowers so yes, it is good news. |

Quoted: I was just specing out all the parts for an E2 build. This may be the solution depending on the timeline for them. @PalmettoStateArmory, any updates by chance? Are we looking at sometime this year or more likely a Shot Show '22 announcement/availability? I do not have any eta at the moment, but will let you know as soon as I do! Thank you, Josiah |
Got my stock, now I just need everything else for this project  EDIT.... I forgot this was already in the retro section... ya'll already know this For everyone else wanting to make an xm177, these had the old aluminum stocks with nylon coating. There are a couple places that have made these over the years, but Double Star recently bought up the leftovers from Essential Arms and is now making their own. Fist batch sold out and they said the next is still a few weeks out. Without buffer and spring With buffer and spring |
This is great news. I have bought several Palmetto lowers in the past, and have had good luck with them. I would definitely buy a couple of these, likely a GAU and an XM177. PSA gets a lot of crap, but they have done more to make ARs affordable than anyone, as well as producing some very good AKs. I'll be watching this thread with interest... even though I thought I was done building.

Quoted: What markings would you want on an M16A1 H&R Retro clone rifle barrel? Never mind, it'll already be on the receiver. Don't mark the barrels at all. If you really want markings, just 12 (for the twist) and maybe a date code. |

Quoted: All, What markings would you want on an M16A1 H&R Retro clone rifle barrel? Pictures would be awesome, but anything helps. Thanks! Josiah ETA - I was referring to the barrel and was not clear. Thanks! Check email in 10 Sent you HR specific photos of MP C I have 6 OG upper/barrel. All same. |

Quoted: PSA, would it be possible for you to post a few prototype drawings of your proposed receiver markings? I’m sure I’m not the only one that would be interested in this. I approve the images before they are put into the CNC machines to be manufactured. I will post those as I can when they come to my inbox, as they are a really good representation of what the lower will look like. Thank you, Josiah |

Quoted: It is being worked on!! Josiah Excellent, I just bought your 11.5 XM177 style pistol and a KAK Industries 6" Retro Flash Hider. I did by an M4 Lower to put with it, but that is easily swapped out. ETA: @PalmettoStateArmory is this going to be a XM177 stripped lower or a complete firearm? |
