Excellent illustrations. My gas adjuster was just too tight for me to use my finger..ouch. I removed the barrel group, grabbed a Bic pen and rested the end of in on the adjuster wings, wrapped my four left hand fingers around the end of the barrel's end and put my left thumb on the end of the pen and pushed hard, on the same axis as the adjuster wing is oriented and she finally complied and moved downward to allow rotation of the adjuster. New gun, Tight parts. Great post.

After struggling through my first take down of the E-4 with the factory manual, I can say that this post is a great help and makes the take down very clear. I didn't lock the charging handle back and learned that the hammer pack won't come out unless the hammer is locked back. My rifle is so tight that standing it vertical on a desk and pulling pressure down in line on the receiver makes pushing the take down pin through the stock a little easier.
sgtlmg, thanks for the great contribution. please follow when you can on your "I'll work on cleaning, lube, and re-assembly pics at some point and/or do a video". It would be great to see the points that you lubricate with the photos you have already taken. I know how to lube an AR but I'm only guesing with the E-4. The manual doesn't give good instructions. Thanks for the help your post gives a new bullpup shooter. |

Thanks for the help your post gives a new bullpup shooter. In a nutshell, put a couple drops on the carrier guide rods, and a couple drops on the top of the bolt at the cam pin. The AUG requires very little lube. |

OK that helps with the general idea. AR shooters are well aware of the need to lube the bolt frequently during long shooting sessions like a carbine class. The AUG bolt is not very accessible through the ejection port, but I'm guessing it's not as big an issue due to the gas system instead of DI. Do you ever find a need to lube the bolt when shooting a lot? Seems like you could get a little oil on the front third of the bolt visible while pulling back on the charging handle.

Do you ever find a need to lube the bolt when shooting a lot? Seems like you could get a little oil on the front third of the bolt visible while pulling back on the charging handle. As you pointed out the AUG is not DI like the AR. The system doesn't blast its internals with hot gasses and carbon like the AR. AR shooters are using all kinds of super-lubes like synthetic high friction motor oil due to the engine-like atmosphere in the bolt carrier. They have to have something that can take the punishment of getting gunked up and having the lube get blasted out. The AUG just needs a light lubricant to keep the action slippery and prevent wear. It isn't necessary to re-apply during a long range session, simply because the lube isn't getting scorched by hot gases. Lube the parts after cleaning and forget about it until the next cleaning. I've run through a couple 40 rd mags as fast as I could, then popped the action out of the stock and held onto the bolt carrier with my bare hand. Try that with a DI AR. |

OK, I figured out how to change the gas port settings (use a cartridge!), but for the life of me I cannot remove the barrel from my STG-556.
I've got the bolt locked back, but I cannot "press down on the barrel lock button", it's seemingly unable to be moved. I've even used the end of a sharpie pen to try to apply as much downward force as possible, but no luck. What's the trick here? |

You don't press it into the receiver, you are pushing it down towards the floor if you are holding the rifle parallel to the ground. Look closely at the button and you'll see that it's in a little groove. Slide it along the groove. |

Edit: Came right off.  |

sgtlmj,
What are you using behind the ejection port to protect the stock? |

I'm about to take it off though. I put it on to protect the stock IF for some reason I didn't warm up to it and wanted to sell it off right away. I'm in love now, so it's time to let her get some character. |

Thanks a bunch for this. I just got my STG-556 today and I don't think I would have gotten it apart without this thread.
The instruction manual is  compared to this thread. |

Very helpful photos for take down. Much appreciated sgtlmj!
One quick question, on the AUG's inside the chamber where the gas piston resides, is that interior chrome plated as well as the gas piston assembly? When I dissasembled my piston, I had a bit of carbon to clean up, but wasn't sure how much I need to clean the chamber, mine is very black inside. |

TPD was nickel plating the inside of their gas chambers at one point. It's not that hard to clean it though. Just use a .45ACP brush soaked in solvent and give it a good scrubbing. I personally use Wipe-Out foaming bore cleaner. I fill the bbl and gas chamber and let it set for a few hours. Carbon wipes out just as advertised.  |

The trigger group retaining pin also works as a tool to adjust tight gas settings. At least on the Austeyr.

Thank you sir for the excellent thread. One quick question, where do you get this "wipe out foam"? I have never heard of it before.
