Those are great ideas and insights! I did major research and found some quality videos of older gunsmiths/builders discussing barrel tuning, and common weak points for accuracy.
The receiver was absolutely not lapped. I also learned quite a bit about testing torque setting for accuracy and found that to be amazing. My buddy just "put her on". No leakage/gas issues but not refined. I found a nerdy gun smith with very high end equipment. I also found some videos of him performing work and he seems like the right guy to take this apart and do a proper install. I will get the accuwasher etc, that sounds incredible. I use an adjustable gas block, but couldn't find a low mass bcg during the time I was rushing to finish the build. That makes perfect sense.
I am currently using a midwest lightweight free float handguard.
Even though I didn't start this thread with pictures... Once we reshoot the upper I will post pictures to show the final result. I bought 130 dollars of premium ammo from the above sources, and then decided it was foolish to shoot it without a better installation and then refining the torque.
Thank you for the education!
