Complete 16” assembled upper options

[peak98]

Got a good buddy looking for a 16” complete assembled upper for his son and wife to use this season. I referred him to a Grendel Hunter or Sanders Armory upper. Sanders was out of stock, GH was a lil out of his price range. I told him I’d check here for recommendations, give it a couple days. He’d also be interested in buying a complete used upper (known good shooter).
What are y’alls recommendations for a complete assembled 16” upper?
