Hey, I'm Kevin, it's my team who make the NJCC projects. I don't post here since, like Unclassified says, I'm pretty well associated on line with Hisstank, but I saw some discussion on our Salvo that I could add to without trolling, I signed up to reply.
I am glad people like the vest, I put a lot more work into it than it might look. It was a combination of bashing and some sculpting onto a Rock sized buck. We couldn't find any vest that actually fit that wave 1 Rock figure that we are using as a base (due to cost). The vest is actually molded to fit over that Rock figure, right down to an imprint of the muscles of his back in the vest. That was a result of the casting process we used. I'm not sure how well it would fit another figure.
The parts are basically the Ripcord/Skydive vest, parts from the Pitt trooper vest, assorted BBI pouches and belts, and the previously mentioned 21st century German pouches across the chest. There are currently no plans by the caster to sell it by itself, but it is always possible another caster could win one and recast it, or someone could reconstruct it.
The "Death Dealer" vest that was linked, funny thing, I made that one as well for 'Spoon to sell. I do like those loaders across the chest. That one is made to fit smaller figures, though. It was much a simpler construction, I just cut up and shortened the vest, and added the pouches. That one is, obviously, readily available.
And thanks Unclassified for the endorsement, I had not heard from you for so long, I thought maybe the Hisstank-OG13 hatred had spread to us not being cool any more either.
Hope some of this helps anyone looking for those parts.
