So a buddy asked if he could come over and use my tools and have me show him how to assemble a upper. Of course he had to have one of those barrel nuts that neither of my armorers wrench's didn't fit and he didn't want to wait. So we devised a plan.....

It actually worked rather well...One bolt through both wrenches and the other just resting between the two.

My experience is you will have a tough time explaining the gas tube alignment to your torque wrench...

I use it to set the minimum torque and then tighten to align. This set up doesn't have the gas tube go through the barrel nut anyway, just had to keep tightening and checking to align the hand guard so the top rails line up.
