I wouldn't worry about Anchor Harvey, every one I've seen has been good. I like their forge mark too. If you look close at that splintered A you'll notice that both parts make an A while the the bottom by itself really is an H. Clever.
The main things I look at in an upper is how well its M4 cuts mate up with the barrel extension ramps. My DD, BCM and PSA are close to perfect so the square forge mark is a good one to have. Other things I like, even though mainly cosmetic, are that the little cap on the upper lines up with the magazine catch channel in the lower and smooth beveling of pivot and takedown tabs. And of course a deep protective finish. (Though much of the cosmetic stuff is done after the forging.)
Anyway, take a look at how your feed ramps line up, occasionally you'll see too much mismatch. Being BCM though, I'd be shocked if your upper is a problem. Of course mismatches could be in the barrel extension too but you'd hope the barrel makers get that part right by now.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together. You'll remember the quality of a gun long after you forget how much you paid for it.
