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:

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.
