Did you locktite the gas block set screws? -Yes

Did you dimple the barrel for the set screws? -My barrel came pre-dimpled and it lined up perfectly.

Did you pin the gas block? Not sure I did, I'm not sure what it means to pin the gas block.

How did you make sure your gas block lined up with the gas port? Prior to placing gas tube I placed block in place on barrel, occluded barrel with dummy round and blew air into barrel and it was venting out unassembled gas block. I then assembled with gas tube placed and did the same thing. Not sure yet if I'm appropriately gassed.

Did you head space the barrel and bolt? I haven't I plan on ordering the go/nogo things just haven't done it yet.

Did you triple check the orientation of the hammer spring during installation? I had a drop in trigger so no. 

Have you shot the rifle yet for function? I put a single round in mag cycled action and fired, then did a three shot burst. Seemed to function as it should and seemed properly gassed for where casings were ejecting right at my 3 o'clock. I still plan on verifying head spacing to feel confident I'm good to go fire a bunch of rounds.
