To start off..........Fuk you Blue!
Now, that being said.

What i have:
Chainsaw Noveske Stripped N6 Upper Receiver *Armalite Compatible*
AR10A lower (Accepts non proprietary mags)
I'm not even sure if that lower will fit that upper. The Armalite "A" pattern is a new animal to me. I know that Noveske used to build their equipment off of the Armalite "B" pattern, but I'm not sure if the "A" pattern will match up.
2.) IF they are not compatible (Novske rep. said that this was for the B style rifle) what can i do to make it compatible? ( i was told a small piece of the upper would need to be machined off to work with the A style lower).
You're done right there. They said that it was compatible with the "B" pattern. That's for us older Armalite guys. Us dinosaurs of the "B" pattern are a slow breed to die. But Noveskse, from what I gather, is still staying true to the original "10B" pattern. That won't fit you're lower.
3.) What manufacturers are known to work with the AR10A lower? (I want something close as possible to an Armalite upper fit)
I'd stick with an Armalite "newer" upper in this case. Just make sure, through Armalite, that it works with your "10A" lower. Probably best to call them.
That being said. Noveske makes REALLY nice stuff. I use their barrels in a lot of my builds. Including their SBR N6 Leonidas barrel.
IT KICKS ASS!
