Pretty amazing concept. I hope the creator keeps working on that prototype. I think Demolition Ranch increased the caliber too high too fast, but still pretty sturdy so far
I'm sure nations are working on something akin to this. At least to field their specialists with over teh cost of armoring a whole army.
I'm working on something similar for my postapo LARPs armor, heavily armored left arm including a ballistic buckler. Nice to see something like this in the real world. I think it would require a good amount of padding, though.
Depending on the caliber intended to stop also structural support, the force of the hit could dislodge the shoulder even if it did not penetrate.
