Basically plan on building around the Aero M5E1 receiver set, won’t run a barrel yet so I can do the 12.5” 8.6blk from Q. What’re the best “internals” for a short AR-10? Bcg, buffer systems, blah blah. My only experience with an AR10 was buying someone else’s build and his puzzle pieces didn’t go together and caused me tons of issues.
 
I've only built one and it functions flawlessly. I contribute that to the combinations of the following:
  • Tubbs flat spring
  • JP full-mass bolt carrier
  • JP high pressure bolt
  • Superlative Arms adjustable gas block
Slowly building another in 22 Creedmoor. The only tunable component is the SA gas block.

Any insight for BCG? The 8.6 trials are being run on a Noveske so I was curious what parts are damn near noveske so the guns are very similar
That I do not know.
The referral to the person in my above post does a large amount of work on specialty projects for the gov and you'll be paying him for his knowledge.
Drop him an email and he'll lay it out for you, guarantee it'll work right out of the box.
