I've added the sling that OP inspired me to get.
This one shown is Troy's sling. But I want to underline that it's the same exact one we'd get on Amazon (shown above) at more than double the price.
The work done to it was to chop off the hooks and swapping those with a nice OD paracord. All work done by Troy's (i.e., you get the sling as you see it here, ready to go with instructions).
The sling smells exactly as the other one you can get more cheaply on Amazon - old and mold - so it's evident that it's exactly the same source of government stock that was then sold off to various distributors. So once and again, they are exactly the same product with the same provenance, the Troy's GAU (so it is marked) being shipped out with nice paracord in lieu than steel hooks.
Very nice.
