So, I decided to run some rounds through the 7.5" .223 SBR upper. I inserted a 20 round magazine, and on the 19th round it jammed and I couldn't remove the charging handle. Once I finally pried it open, this is what I found.
I spent quite a bit of time looking over the failure trying to figure out what happened
on the last page there is a video of the gun firing.
