Adjustable block isn’t necessary but it’s not gonna hurt anything. Uppers are super easy to assemble but if you don’t want to fuck with it see if you can find one assembled but without a hand guard that way you can at least get the hand guard you want and not have leftovers.
I’ve ordered a few barreled uppers from MAS Defense and they work fine. I don’t like their hand guards tho.
Is adjustable gas block with the cost of you're gonna run suppressed and unsuppressed?
I don’t have an adjustable on any of my guns so I don’t know first hand. The only time I see it might be worthwhile is if you want to run subs unsuppressed. Someone with more experience should probably weigh in.
From what I've read it helps reduce wear on internals from overgassing, which also keeps those gasses from getting into your eyes.
