They are both 'high shelf' fwiw... (no DIAS for you!) lol
ETA: I have a spare stripped S&W, I sold my old-school 'factory-tuned trigger' NM RRA setup lower and do not miss it. The RRA trigger was fine for great for target work though, and if used hard enough for long enough it will revert to single-stage operation.
'Matched' uppers & lowers at the larger mfr's usually means there is a person going thru a big stack of each to find ones that fit together ok.
S&W ARs used to be made by Stag, but now they make their own. They even do extra machining inside the magwell to eliminate sharp edges which is not a deal-maker/breaker but is a nice touch.
I'm pretty sure my old RRA was a LAR lower, but does it really matter?

My guns were claimed by an unfortunate smelting accident.
