Kaveman,
I'd also be mindful that as the barrel nut is done up that the extension doesn't shift with the nut as the torque gets applied. Once you've got 40 ft lbs applied it should resist rotation with every round fired. Each bullet is not a lot of axial torque but it will be relentless, for the life of the barrel.
You could just carefully put it together and see what happens. It's not a safety issue.
