Well, that was worth a look.  I might have to print that off even if for no other reason than the torque specs and tightening procedure for the 6940 barrel nut.Thanks OTDR! I did see some odd torque specs given for RIFLE receiver extensions/buffer tubes and very wrong installation procedure for the crush washers. Also, (as has been noted before) Colt's listed torque spec for the pistol grip screw is insanely high at "60 - 65 inch pounds". Whoever wrote that must have been drunk... No more than 30 - 35 inch pounds and 35 is pushing it considering the polymer of the grip. |

A subscriber to my Youtube Channel left this comment about the Colt Armorers School: ------------------------------- So, I just finished the class yesterday. First and foremost I would like to say that there is no stress. There was an exam at the end and a few practices, however it was not so bad. No one failed. 2nd, this course is valid every 3 years so I was in a class with other students that were much more knowledgeable then I was. This meant I was left behind. However, the instructor and students helped me out when needed. On to the course…. The first day was a lot of “ Sea Stories” (well police stories anyway) that pertained to the AR. We did some introductions and took a pretest. We went over the history of the gun (briefly) the different models that came before and the current models. The first half of the day was just talking and teaching. After an hour lunch, we came back and grabbed the rifles and took kits (all provided by the Colt to use, not given). We broke down the bolt assembly all the way down with exception of the staked portion. Then, we put it back together, then again and again. We finished the day off around 3pm (started at 8). Being in the military, I was pretty familiar with the bolt carrier group, I can break that down and throw it back together in no time. I felt pretty confident going into the second day. That did’t last long. Day 2 was the lower receiver, I have never touched that before, I always figured with was some kind of fairy magic and I don’t have to worry about it. Seems that isn’t the case. You start with the hammer then trigger assembly then on and on and on, I was taking out the pivot and takedown pins, the mag release, bolt release, pistol grip, I had springs galore. I got lost real quick. Putting this this back together was not a walk in the park. You literally have to do it at least 10 times before you can get a handle on it. But, we would go over a section and do it multiple times. Go over another section and do it multiple times. Before I knew it, I had a pile of time parts and time springs everywhere. However, we did it enough so I would know what is what. It was actually pretty freaking awesome. Day 3 was the upper receiver, barrel removal, practical, and exam. There are not as many springs but definitely takes time to learn how to manipulate the parts of the upper receiver. The day starts off by taking everything apart then switching seats with someone to put their gun back together. You learn by repetition, the more I did the better I got. After lunch we took the barrel off, did the practicals where the instructor created a malfunction int he weapon and we had to find it. Then we went over the maintenance of the AR / M4 and did a test review. Then we took the test (like 20 questions) and course evaluation. Fin. The test I think is a formality. But, when you see a pile of parts on a table and you can identify where each goes and how to put that weapon back together, that’s where the real gratification comes in. The course itself is great. I took the law enforcement version so your class may be different. All in all the course is well worth it. |

| Very cool. Thanks, op. I love to nerd out on user manuals. I’m that guy who reads them cover to cover before using the tool. |

Are there any other discrepancies that guys like me that are starting to do more involved work on their rifles should be aware of? @OTDR @556Cliff |

Still alive, was just taking an ARFCOM (and social media in general) break. That stupid ban has taken the wind out of my sails a bit too.

Your not taking IMs either. Bunch of the last green Hulks came thru discounted due to being blems lol! Ha! No need to sound the alarms, I was just taking a break from here and other social media. Figured it would be better to have my IMs off while I wasn't checking in here. I have been watching the green jigs though, I was surprised they had that many blems in the anodizing on that last batch... As hard as it is to resist, I still haven't ordered a second one. Those ejector cut headspace gauges from Forster have got my interest and I'll probably be ordering a set of those on my next Brownells order. |

It's another one of those things where I'm surprised it took so long for them to come out because it's always seemed like there's been a demand for them. |
