Works with Aero BAR nut after modification
It's a solid piece of metal, the pins are secure and the slots are nice and tight. To use this on the Aero BAR nut, like the other reviews and answers, you'll need to grind one side of one pin to reduce the outer radius, then it fits nice and tight on the BAR nut.

The Correct tool, compared to all else
This is how a barrel nut is supposed to be made. The description is clear, as stated this is a copy of milspec wrench. i am a US Navy Armorer, and it looks identical to my tools. i doing any standard profile barrels, 20" 16" 14.5" 10.5" quality barrels with a standard designed barrel nut. buy it. dont wast money on the huge long does everything wrench's, i have seen truly dozens break.

A good tool to have
I bought the combination wrench to change out a muzzle device, and it worked great. I did not even need to torque the wrench that hard to loosen and tighten muzzle devices. This tool also has a great combination of other uses and is made of thick steel.
