  1. Why do you think a reaction Rod is good because if you are an actual gunsmith you would not think that it was good they do not hold the receiver you're talking the barrel nut to the receiver the only thing you're holding is the barrel

  2. Doing an Aero build now, standard upper with this barrel nut on their enhanced quad handguard with an Aero barrel as well, all I can say is what a pain in the ass have used every shim they gave and its still no where near lining up with nut and the tube port, i need to call and order another shim kit.

  3. I'm a lefty doing my first build with the Aero gen 2 picatinny handguard and bar nut and Stag upper. . I'm here because I can't figure out why when I try (about 40 tries) to install the barrel nut it's not lining up with the hole in the upper receiver for the gas tube. Is that what the shims are for? And why don't you guys include shims with the bar nut when bought with a handguard? I just looked on your website and the shim is $6.88 w/tax + $11.19 for shipping (cheapest shipping option) Now that's plain stupid. So stupid I don't even want to use the dam thing. The only reason I'm still trying with this is because I bought the M4E1 lower and a bunch of other Aero parts.

  4. The AP Bar Barrel nut three hole positioning is not compatible with a good number of standard armorer's wrenches. I wish they would post a link to all wrenches that are compatible and let the buyer chose which one to use. I bought one that is suppose to work (based on customer feedback) but the three pins did not align, so I just used two pins. Not the best solution but I have yet to see an official recommendation from AP on compatible wrenches

  5. When using a torque wrench on a armor wrench like that it’s better to have them both inline with each other. Compound angles like in the film mess with the torque spec.

  6. Need to work on presentation of these videos. I like Aero Precision but all of the videos I have watched are poorly produced. Lighting on the Aero Precision videos is poor. Why didn't you show the installation of the barrel and discuss the rings or washers you added. Audio is too fast and at time inaudible. Could barely understand the torque values you were using.

  7. I think for 1st time builders you need to explain
    a) what you are "Indexing" and why
    b) Why you "Season" the barrel nut

    It's like when you 1st show your child where the dipstick is, and a week later they ask if there should be oil on the end of it. We take for granted people know the why of things.
