I have a flat top upper I was planning on using in an up coming build. The only markings on it is a small key hole design on the side. Anybody know the manufacturer of this upper?

I think Cerro sells forgings to many companies, my CMT/Stag upper has the same keyhole markings. So I guess this question could be two parts 1. who forged it? 2. who machined it? Thanks Frens, I always thought it was just a stag upper...never thought about who the forger was.

Essential Arms uppers have the same mark.  Glad to know that they are Cerro too.
