The factory stated it is a forging alloy similar to 7075, but not 7075
This is the answer I expected. 7075 alloy was developed by the Aluminum Association and is governed by a US specification, the chinese usually prefer to work with British standards or their own. One lab I used to work at routinely saw mild steels from China that were consistent, but didn't exactly match any American mild steel specification.
I am not sure which one you have, or how old, but I saw the forgings being put in the CNC machines at the new plant for ours. This was the same visit where I asked about the alloys.The upper and lower on my CQA were not forged....lower is cast, dunno if the upper was MIM as poster stated above as I sold it instantly.....
It's lighter then my other 6061 and 7075 lowers as well if that tells you anything.

Its main alloying element is probably MSG.
They were probably rebranded Chinese junk!
And many of the MIM parts for the lowers are made in India.close to 30 % of US ar15 parts are made in Taiwan, about 5% from Korea
.......which of course makes you hungry for more Chinese AR's![]()

MSG and high lead content! What could go wrong! You could invade pot smoking North America without firing a single shot. Now that's tactical!
Great entry AR. Really helps open the door for many who wouldn't be buying one otherwise. It's a gateway AR!
Has anyone ever seen a norc lower or upper fail? Im just curious
