Lower Receiver FAQ

Thanks. The post I am looking for has a large number of companies listed. I just can not remember where I saw it.

Quoted: CMT, Continental Machine & Tool is a big one. They forge receivers for several manufacturers including Colt.

This is incorrect. CMT is a machine shop who machine forgings from various suppliers.

Here are a afew forging companies.

Cardinal (Cardinal head)- www.dekalbforge.com/cardinal/index.htm

Cerro (key hole) - www.cerrofabricated.com/index.htm

I believe the "spliner A" marked uppers are Alcoa.

My mistake; I should have left out the "&." I have a CMT lower receiver that is very well made. So, are you saying they only machine receivers forged somewhere else?

CMT Military firearms division.

Yes, CMT, LMT, LAR, etc all buy raw forgings from foundries to machine. You are not going to set up a foundry just to forge AR receivers.

No a splintered A is Anchor Harvey

OK, now for a question that I should have asked earlier.

I know what the casting process is, however, what process is used to forge an item such as a receiver?
