I think I've narrowed my choices to these two uppers.
I will be running a suppressor 99% of the time.
Both uppers have their own benefits, but in your opinion, which and why would be your choice for a dedicated suppressed upper?
Thanks!

of those 2 i would take the Noveske.

1) i'm not a fan of piston ar's

2) the DI upper will be a bit quieter than the piston upper

3) it's Noveske , so it's bad ass approved

This. If I wanted a piston system, I'd get one that was designed from the get go as a piston system. YMMV

I went with the LWRC 10.5 rifle after looking at both guns at Rainier Arms. For me it was price, piston upper, ambi lower and I prefer the rail setup. I have a 14.5 LWRC IC and a 14.5 Noveske with S/B. Both are great rifles and both handle surpressed fire fine. But for me the edge goes to my LWRC and the Noveske stays in the safe now. Between the two you cannot go wrong.
