I strongly suspect that if the Knight's fits, any of the DPMS type uppers would fit as well, but it may vary since there are no official AR-10 specs, unlike the AR-15. Use one that takes the SR-25/DPMS type mags, like the ones made by Magpul.

You may have to experiment by trial and error. Generally, all of the AR 7.62 rifles are potentially interchangable except for the Armalite AR-10.

All you are really looking for is a barrel swap into a properly assembled precision upper, correct?

more of upper swap. To have a designated upper (was planning AR10) in 6.5 CM. So with same Larue lower, I have 7.62 OBR upper and a 6.5 CM semi upper.
So I definitely won't be using Armalite lower
