Agreed. Anderson, BCM, and Palmetto all have their uppers contracted to Anchor Harvey Aluminum. There is no quality difference and as far as uppers are concerned, not even a roll mark difference. I wouldn't be surprised if the lowers for those 3 companies are also manufactured by the same company.
The uppers from Anderson I've seen have came from Cerro, same with their lowers.
Anderson makes receivers for other companies, but they stand by their word when they say they don't make receivers for PSA
Ok, lowers might be different but my Anderson upper has the same "splintered A" just like my BCM upper and my Palmetto upper.
I bought one for a build the had the back radius screwed up. It would be that noticable if I had an adjustable stock and oversized pistol grip, but this build has a2 furniture. It is bothering my OCD a little bit
How old is your upper? The past 5-6 uppers of theirs I've seen (including 308) have the keyhole
