If you are asking for a tool to tighten the barrel nut on, don't use one of those, seen a lot of threads where people have screwed up their receiver, or sheared the barrel pin off.
Use an upper receiver cam shell holder. |

Thanks, I am open to other tools as well including clam shells. My preference would be for the midwest industries rod though as it has the added extension for the charging handle channel to take the stress off the index pin. At least that is my understanding, still a novice with this stuff. I agree I wouldn't want to just use a standard reaction rod without that extension though for torqueing down the barrel nut.

Is it a flat-top?

Yes it is a flat top, but I don't think I have the balls to try a set up like that.

One has features to prevent what you said while the other does not. Midwest Industries Geissele |

Two pieces of wood and a decent sized bench vice also work.

Doing nothing with an AR15 actually, going with an AR10 to maybe give me a little more balls? In all seriousness though, why fault someone for choosing to use the proper tool to build a $1500 firearm as opposed to jerry rigging something up that could work, and certainly has worked for many in the past, but still presents potential to screw things up? When you spend enough time using hand tools one learns you should always use the right tool for the job. |

Lol thanks, I am not sure what barrel nut system to call it other than whatever Larue Tactical uses on their ultimate upper kits. Probably some proprietary system, although don't quote me on that. They do provide the barrel nut wrench though. And I actually just ended up ordering one of the Midwest Industries 308 upper receiver rods myself, and figured I might just flip it on to someone else after I get my upper built up. |

I have a vise block in the north metro, it uses the takedown and pivot pins to lock the upper in place.
vise block Nevermind, I didn't read the full post above this one... |

Just use 2 pieces of wood in a vice, barrel wrench and torque wrench. Because those are the right tools for the job. Every build I've ever done used exactly like that. Anything else is unnecessary eye candy, for self gratification and a small amount of added convenience.
Those upper receiver blocks that only attach to the takedown pins without reinforcement within the upper receiver itself are known for causing damage to the upper. 2 blocks of wood provides full support. Don't get hung up on insignificant aspects of a process. 2 blocks of wood takes care of the deal and with no drawbacks. |

No thanks, I'd rather use the right tools that one person's opinion that thinks is eye candy, yet is really functional and is very much worth the coin I paid. Plus as an added benefit, there's no way to over-torque an upper sandwiched between to blocks of wood pressing inwards with nothing to keep the inside reinforced.
But you do you. |

Just consider buying the MI rod -- it will be of use for muzzle devices & resale price is often great.
I've used the much cheaper Brownells 308 extension tool once which sucked for mounting to the vise. Funny thing, my Optics Planet backorder for the 308 MI Rod has finally shipped so take a look over there. |

Use an upper receiver cam shell holder. The last thing I would use is a clamshell. Talking from experience with the ar15 version, the MI rod has a metal tab the supports the upper from inside, and I have not had an issue seeing widened index slots even when loosening tight barrel nuts. The Geiselle rod tended to cause deformation to the index slot pin if torque exceeded 60-70 ft/lbs, but I prefer to keep it around for muzzle devices as the MI model requires the upper locking tab to be removed to clear the gas tube which is just tedious. |
