They are not. If you go inline you will vastly over torque.

Put the torque wrench 90 degrees to the nut wrench and its one to one. When they are end to end it multiplies the end torque based on how far the nut wrench extends. There is an equation to do the math but its easier to just 90 degree it

Sorry JonM, glad you caught that. That's what I get for assuming that everyone knows to put the AR wrench on the torque wrench at 90 degree. Didnt even occur to me that someone would try to put it on inline. Guess you don't see the obvious when you've been doing it for so long....

They say assumption is the mother of all f%&*ups....

I am working on my first build and just got the barrel and gas tube installed, I was checking the bolt alignment and now the bolt is stuck and will not come out! Any suggestions.
