I'm having (5) bolt carriers manufactured using HY-100 steel. This is the same material US submarines are made from and are virtually indestructible and resistant to corrosion. The steel is certified MIL-S-21952 C/D and T9074-BD-GIB-010/0300 and rated at 100,000psi. You can read more about it here: https://en.wikipedia.org/wiki/HY-80. Our company manufactures replacement parts for the Ohio Class Submarines and I had some material left over, the material I have has been ultra sound, X-RAY, gamma irradiated and stress test.
Having said that, I am wanting to know if anyone would want to test these out for me. Possibly a few thousand rounds should provide enough feedback. Basically I'm wanting someone to try to destroy these bolt carriers through heavy firing, wet/humid conditions, carbon build up, different types of ammo etc. I don't know if there is a market for these considering these would probably cost around $400-$500 but perhaps last a lifetime. Anyways, let me know if you have interest or wanting more information.
