How important is torque on barrel nut (AR15)

I recently obtained a hand guard that did not have the standard Barrel nut, it is like shown here:

The supplied wrench is a flimsy thin affair, and has no option to attach torque wrench. Supplier indicates it will get it sufficiently tight... Being paranoid about things like this, A ordered a set of crowsfoot wrenches with a 1/2 drive hole to fit my torque wrench.

Darn it, the crowsfoot wrench is too wide to fit in the provided slots. Figuring an adjustable wrench would be better, I found one that opens to a max of 1 1/8ths inch, and was still thin enough to fit the slots on the barrel nut.

I tightened it, loosened it, repeat, and then snugged it up as good as can be with a wrench only 8 1/2 inches long, but tighter than the little punched wrench that came with it.

Of course I am nervous about things like this, I like things like this torqued...typically 30 lbs, back off, 30 lbs, back off then to 30 lbs + what ever it takes to align the gas tube, usually 40-50 lbs or so, closer to 40.

I am over analyzing this, or is my worry well founded? (yes, proper stuff on barrel nut threads and so forth...)

I have another set of crowsfoot wrenches on the way, hopefully they will fit...

Thanks, I have heard from several who used this wrench included and it worked for them.
I know I got it tight as it would have allowed.

The guys I got it from told me they are redoing the barrel nut so that the part that the wrench goes on will now be on the outside edge, so my wrench wouldn't have a problem, nor would anyone else.

Sounds like problem solved!
Thanks again,
