Barrel nut compatability PSA10 Gen 2

[albersondh]

     On assembly the barrel nut broke at 50lb/ft, so that sucks.  I emailed PSA because they don't list this as an available service part.  Im hoping they have some spares and will sell me one.  I like the nut because its very low profile and doesn't require gas tube alignment.  If PSA wont sell me a spare Ill be looking for an alternative that will work with my upper, barrel, and hand guards.  Assuming PSA gives a negative response, is the barrel nut thread, diameter, ext common?  Or is there any other nuts known to work with this upper and hand guard?  Thanks.

For reference, a suitable replacement nut:

This one calls for 45ft/lbs.  The PSA stock nut is 6061, this JL nut is 7075.
