For the sake of discussion, what might the unobtanium be put to better use for? Triggers, cam pins, parts for another firearm? Just wondering...

I am just surprised you were able to source the leftover HY-100...
ETC (SW/AW), USN (1998-2008)
CVN-65, USS Enterprise
I’ve never worn out or broken a carrier, and I can’t recall ever seeing one get broken. I did see yesterday what looked like pitting or chipping of the chrome bore of a M16A2 carrier, but I would assume its from 30 years of knuckleheads using crazy $&!% to clean it. The gun does not appear to be having any malfunctions today.
So, yeah, it would take me forever to destroy a carrier. I can break a bolt for you, though.
HY-100 is lighter than 8620 carbon steel, Carpenter 158 and Super Duplex. I know that machining HY-100 is not easy, but doing some research and talking to our engineers, I have found that HY-100 is perfectly suitable for a bolt carrier. The reason is because HY-100 is used primary because it is resistant to corrosion, light weight and stronger than other bolt carriers on the market. It would cost me $400-500 to manufacture (5) total, not each.
I don't have the capabilities to manufacture the gas key, bolt, ejector, firing pin or anything else for that matter. I am just going to do a run on the bolt carrier itself and then buy the parts needed to build a complete BCG.
I also don't have the capabilities to chrome line the bore so I will most likely use Ceramax which is a coating that we invented and later sold to Rexroth, more info here:https://www.airlinehyd.com/literatur...%20Coating.PDF
its stronger than chrome, more heat resistant and self healing.
this is a drawing I did on AutoCAD Inventor

I have a drawing for the bolt itself, just too complex to manufacture.
Isn't lightening the bolt carrier generally considered a negative?
Manufacturing anything for the military is kind of a pain in the ass. Sometimes we cant buy exactly what we need, say we only need 60 inches of material, we have to buy a minimum of 100 inches. That 100 inch bar stock come with ISO documentation and certifications. The docs and certs go with the 60 inches worth of material leaving us with the rest of the 40 inch bar stock with no paperwork. So if the government orders an additional part, we cant use the 40 inches that was left over because it has no certs or docs. BTW, this is a company that I have an ownership in, my dad who is now gone, was the owner.
The one thing I consistently see with carrier bodies are damaged/loose keys. Damage is usually from dropping carrier, keys coming loose and slamming into gas tubes, people sticking shit into carrier keys attempting to clean magical carbon fairies out which results in things like cotton tip heads breaking off (wooden type) inside.

Looking at this drawing I made doesn't look hard to manufacture, but in reality, I think these are forged into there primary shape and then machined finished.
Attachment 50417
same with the bolt itself, I think these are forged into shape then machined finished using maybe a broach, lathe or a mill , I don't have the tools to machine the lugs.
what I have is CNC lathes and CNC mills and a broaching machine for making keyways
Not that lighter is a good thing but how much lighter is lighter? 1%, 10%, 50%. Is corrosion a problem with the common phosphated carrier? Last ?. Tell me about this self healing Ceramax. Does self healing mean if I wear it off today it will grow back tomorrow? Kinda like a skink's tail. Sorry if I sound skeptical, but I am.
