It appears to be an Aero M4E1 enhanced upper. As for the rail not being level with the upper, if you look close in pic#2 I see the barrel nut threads. I don't think he has the rail over a barrel
nut, causing misalignment.

I created some confusion (I added a note to my original post), the rifle is not assembled, so the gap is not a reflection of the handguard or upper fit, I simply put them together for an illustration. I do not anticipate any fit issues.
It was just interesting the markings on the handguard, it just seems to me that on either my Spikes or Aero uppers a T16 marking should be the first on the handguard and not T14. I don't plan to even contact BCM, I am sure there is a reason for doing it the way they do and on my gun it will be mostly obscured by an optic anyway. The HG is beautiful by the way.
The correct (ala Mil-spec) is that the T-13 (unmarked) is the last slot on the picatinny top rail. Notice how the area above T-13 COULD fit another slot, but it doesn't. I don't know why it doesn't, but per the TDP it is uncut; thus T-13 is the last slot. See below for correct/mil-spec upper receiver...

I've seen a few "boutique" ARs with misaligned rails. I would ask DD to fix it.

Trying to get DD to fix a non-DD product/assembly seems like an odd piece of advice.
