Ii noticed on the upper picture you have a LMOS Bolt Carrier. I also have one on my build. Do you have the Silent Capture Buffer Spring or JP Low Mass Buffer in the buffer tube? You may want to go that way and set the gas block more closed at first and work your way closing it gradually to feel the recoil increase till it cycles properly.
If I sound like I know what I'm talking about I don't, its all just information I'm passing along i got from JP CS. I also have the same set up with a 24" barrel but haven't got mine to the point your at yet but did talk to the customer service regularly as I gathered all the parts. They said that is how to set it all up together when using the LMOS Bolt Carrier, with the adjustable gas block and correct buffer. It's much lighter than the Mil-Spec Bolt Carrier so I'll be looking for an update from you.
Looks great and really like the heat sink under the hand guard. It should be a smooth ride.....
