Yeah, I have a ton of input, but the bottom line is, it should work. I wouldn't put all your eggs in one basket on your barrel manufacturer, but that's my opinion.
I have full Armalite AR-10 guts running inside Aero Precision M5 receivers, and it's badass - so I know that of the cross between the two platforms (Armalite and DPMS-based) is done right - then they work right. Nutshell version, right there.
Be ready to run Armalite AR-10 mags that work in the 10B platform. Mags that typically run in the 10A platform will not work.
