Does 2 Unique sell the wrenches? Cheaper than the linked Brownells? Quote HistoryQuoted:
Quoted: > a more affordable version of the jig. Key factor here. 2 Unique LLC makes the barrel wrenches that are in use at Windham Weaponry. They do not have a barrel extension torque tool that can be attached to a torque wrench like Brownells though. The JC Machine and Motorsports jig is $350.00 and that is the price to beat when 2 Unique comes out with their version. |

That's really nice! Magpul and Geisellie are rushing to the drawing board as we speak. "Something is going to lock up first with that thing. Barrel extension or receiver, it never will be both at the same time. Classical over constrained system." |

It was one of these drainage ponds like the pic, not sure which one though as I used to run the golf course when I lived in the Security Hill barracks. As for age, I have no idea as I found it in 99 and it looked like it had been there a while and settled down in the mud at the bottom. I only saw it when the water was receded quite a bit.

That’s close enough to the flightline that it could have been ON the flightline ‘in the day’. When and why it was dumped aside, that jig must have traveled quite a ways to wind up dumped there. |

I used to work across from the CATM guys on Medina. My neighbor was actually CATM there a few years before I got there and had never seen anything like this. Since it was on Kelly I'm wondering if it was something from the CATM shop on that base instead of from Lackland. I think the old SP headquarters had been on the other side of the flightline, more like around the old Finance building (though I could be quite wrong - they moved everything around to mess with me  )

It removes any stress from the pin and keeps the upper receiver loaded to prevent movement. BTW, I've had an original Reaction Rod for a few years now that I've used hundreds of times (I'm serious, I use it almost daily) and I've never sheared an index pin or stretched the pin notch in an upper. Maybe I'm just lucky. That, or I use my brain and realize the limitations of the tool. That said, this pond find does look like an improvement over either Reaction Rod design and also wouldn't have to be mounted vertically. I'm betting Tigwelder1971 could fairly easily build these jigs and market them for much less than JC Machine's $350 jig, while still earning a good margin. |

Most of the indexing pin shearing issues that I have seen with the Reaction Rod come from trying to remove a stuck/stubborn barrel nut, where the friction between the threads of the barrel nut and the threads of the upper receiver exceeds the clamping force between the face of the upper receiver and the barrel extension flange... Indexing pins shearing during barrel nut installation has happened too, just not nearly as much as during barrel nut removal. |

Quote HistoryQuoted:
Yes, the Super Reaction Rod does eliminate those issues but you can only apply torque in one direction at a time unless you reset the brass wedges between every tightening and loosening. It's really a pretty fiddly system to set up and it's not quick and easy to use like the standard Reaction Rod.

Indexing pins shearing during barrel nut installation has happened too, just not nearly as much as during barrel nut removal. I've removed quite a few barrel nuts on factory assembled PSA uppers that required me to use a four foot breaker bar and my 225lb ass hanging off the end and I've still never sheared index pins. Don't get me wrong, I've seen pics of these sheared pins, but I can assure you that it only happens when someone is being seriously stupid, the pin was soft, or something was seriously f**ked up. Now, with all that said, I'd still like to have one of these pond jigs.
ETA: BTW PSA, I know your shop monkeys assemble 200 uppers a day, but please start having them grease the receiver threads, season them once or twice before final torquing of the barrel nut, and give them a torque wrench. I swear they must have gorillas in there installing the nuts on their FF handguard uppers. Dry as a bone and tight as hell. It's ridiculous. |

Quote HistoryQuoted: I understand what you're saying about the Super Reaction Rod, but I disagree about it being "fiddly". In reality all you have to do between tightening a barrel nut and loosening one is to tighten one allen screw on the rod and loosen another. Tightening one screw moves one brass wedge out of the way and loosening the other allows it out to make contact with the opposite side of the upper's ejection port. I undersrand that these barreling jigs don't require any of that, but for home builders and even most armorers, they're just fine. None of us are on a line barreling uppers all day. For those guys, you have barreling jigs like the WW one. I've removed quite a few barrel nuts on factory assembled PSA uppers that required me to use a four foot breaker bar and my 225lb ass hanging off the end and I've still never sheared index pins. Don't get me wrong, I've seen pics of these sheared pins, but I can assure you that it only happens when someone is being seriously stupid, the pin was soft, or something was seriously f**ked up.

I swear they must have gorillas in there installing the nuts on their FF handguard uppers. Dry as a bone and tight as hell. It's ridiculous. I rounded out the hex drive slots in the two screws after 3 barrel installation jobs and I realize that this says nothing about the "fiddlyness" of the system but I would have to get some new screws to make it work again.
Maybe a lot of it really comes down to the quality of the indexing pins being used, but I wouldn't really want to rely on the quality of the indexing pin for anything more than the alignment of the sights on the upper receiver and barrel... The upper receiver's indexing pin notch will deform before the indexing pin shears, and if the notch becomes damaged there are ways to deal with that to "fix" your sight alignment but I would rather not have to mess with any of that. I have heard that quite a few times about PSA assembled uppers, reading about the various issues with them on the forums their assembly quality seems to be pretty poor. |
