Forged vs. Cast Steel


Can you then comment on why Springfield continues to use cast receivers for the M1A? Don't get me wrong, i've had several cast SA receivers over the years, as well as other brands. I've never had any issues related to them. I also don't put that many rounds through my M1A. The trend now though seems to be towards forgings again for this part. What is the life expectancy of a cast M1A receiver vs. a forged one? What is the cost difference? In light of Springfield's reliance on forgings for 1911 components, which arguably are far less stressed then an M1A receiver, why the casting?
