Quote HistoryQuoted: It would be nice if someone made a castle nut wrench that was thicker/ wider where the torque wrench inserts. The torque wrench seems to wobble in that area because there is not enough real estate to encompass the entire 1/2in or 3/8in shaft. https://www.ar15.com/media/mediaFiles/278288/B2AA9917-9338-441A-BB0A-2016F7F83A22_jpe-2385481.JPG  Attached Filenotice in the pic that the assembler is using his thumb to keep the wrench seated on the castle nut. this is critical. this being the case, you do want a slight bit of allowance so that the strong arm of the torque-wrench arm doesn't unseat the wrench and the applied thumb pressure. sometimes when you're applying the torque, the human arm doesn't move in a perfect arc in the plane of the castle nut rotation due to the combination of all the multiple joints, disturbs the wrench from being fully seated. need to allow for that. now, a robotic arm wouldn't have that variance. JMHO. |

JMHO. It is much easier to keep a wrench or anything with a handle/ arm straight if it’s acting as one piece. Once you start adding extensions, adapters and so on that have movement/ wobble, it causes issues. |

I'm glad I found this thread a while back. Some good recommendations for jigs and such. Had an AR I built years ago when I had my first go at it not knowing any better and did a janky job of it. Buffer tube was crooked, something was up with the front site base being canted as well.
Ended up going with the VISM/NCSTAR jig for the buffer tube which I found on The Country Shed, got a Midwest Industries Receiver Rod, and also a Brownells receiver face lapping tool. After rebuilding the whole setup using the jigs and proper techniques all the way down to the thread lube for the barrel nut threads, everything is straight and squared away. The blue buffer tube jig really is a nice buy for the money. Appreciate all the info put into this thread. Now I have a nicely built gun and not some ghettoness. |

Quote HistoryQuoted: I went with this https://botach.com/kz-ar15-m4-receiver-extension-buffer-tube-block/ It doesn’t have the tang to connect to the lower receiver itself. But I have not had any issues applying the 40 ft lbs and clocking. I do use the grease as specified on the threads as well as stake in two places while held in this tool. You can use this tool as well in four different orientations if you are wanting to hold a lower for any sort of work. Did Botach fix their shipping "difficulties"? |

Keeping the Receiver Extension aligned while tightening the castle nut is a problem? I can only think of one time in about 25-30 assemblies over the years that I ever had to redo the assembly of the RE because I was distracted.
I keep a LOT of tools for AR assembly, but that one is superfluous. Its so easy to eyeball the RE and very slight misalignment will not make any difference as long as the buffer retaining pin is aligned properly and not binding on the RE. That's it. This is a tool for the anal-retentive types LOL. |

I have spent $40 on specific tools like a castle nut specific wrench, $40 for a alignment jig that can also be used for other miscellaneous tasks is no biggie. I have never had to redo an “assembly” but a handful have had a very slight cant that technically caused no issues but for the price of the blue jig, it’s a no brainer for me. |

I really like mine, I like my modified screws, springs under the cap, extended length pistol grip screw, and shimmed tower. So not much fiddling now, slide it in and tighten it down. I modified both of mine identical. |

Partially assembled a couple lowers today using the big GREEN jig! I'm here offering a picture for proof.
It's awesome and worked perfect! The receiver extension alignment is dead on and there were no modifications required... For the price I'd be pissed if there were. Anyways, finishing these 2 lowers got interrupted by a short notice call in for work early tomorrow morning and that ruined my mood for completing them. Plus I launched a Geissele SD-E disconnector spring into another dimension while I was trying to seat it in it's pocket in the trigger... I don't have the greatest luck in seating those damn things, so if anyone has any tips that would be great.  P.S. I went ahead and attempted staking the end plates on these 2 even though I did not have good results on the last ones I staked due to the Colt end plates being overly hard. To my surprise it went well this time around, even though I'm using Colt end plates from what I assume came from the same batch. However, I changed my procedure to only stake in one spot instead of two, since staking in 2 spots can make removing the end plate from the buffer tube near impossible without damaging the threads on the tube. Of course you could always get the Dremel out (the one tool I don't have) and cut the end plate off.

Quote HistoryQuoted: That is not really that much. I would be more worried about the wrench I used not slipping off at 40 ft lbs than the jig. I watched the video people mentioned and it looked like the wrench slipped off the nut at the end as it was being tightened. Other wrenches possibly slipping off, but not this one.

The instructions make it sound like you loosen the screw for the grip tang fork and just fold it out of the way for use with AR-10 type receivers and use it like a Geissele reaction block. Your picture shows otherwise though, so maybe you could clear up the confusion for me? It looks like you just flipped the grip tang fork upside down and that's not clear by reading the instructions at all.
