Also understand that one reason that the DPMS/Rem. receivers are
so heavily built is that these receivers are extruded and not forged.
They build the receivers thicker to make them stronger, which adds weight.

You are right. .. the forged lowers are stronger, that's the ArmaLite selling point. All I have are ArmaLite, and they are nice weapons. There's not a noticeable difference in weight. As far as the Dpms receiver I have never seen or heard of one failing or cracking. As far as the magazine issue, ArmaLite designed its own magazine.. DPMS is an AR 10 specific magazine. . If you want a magazine that can be exchanged between rifles go with Rock River Arms they are FN magazines. RRA also uses forged receivers.

MSH... Did you just try to sell that extruded aluminum is stronger than forged? I just walked into the engineering office here, and showed your post to the extrusion department engineer on duty. Out of respect for you I will not quote him.. As I was informed you are partly right. He rather colorfully pointed out they are just different ways of forming aluminum. Forging is a compression process that results in a much denser component that is harder and stronger per the same aria of web. He stated that you would need a much thicker extruded component to equal the durability of a forged component. The reason your extruded receiver takes die better is it is a softer material. Further he told me that hard coating doesn't increase the durability of extruded aluminum at all. It will offer corrosion resistance. Also stated that any reputable aluminum manufacturer can easily prep forged material for coatings. It will be hard for an average person to accomplish in a garage though.

Ok I think I misunderstood your first post. I agree 100% now.. I don't think there's 10cents difference between the different receivers out there because those who use extrusion or billet compensate with thicker walls.. I was informed that forged will flex then crack, and extrusion will hold to failure then bust apart.. in such the thinner forging would flex (bend) at a lower pressure than the thicker extrusion would bust. So the forging could fail first..
