What specific upper receiver features do you need to run 9mm?
My current favorite is my AR-9 pistol build ... 8inch barrel with a NFA complete lower ... Did upgraded the trigger to a POF drop in trigger ....using a Kak shockwave pistol brace ... love it

I see that relatively recently Colt added 9mm ar again to the line up. Used to have a colt sporter lightweight ( fixed handle a1 sights) that I enjoyed and was very reliable. How do these new models compare?
Not much different actually.......just the updated receiver.
Proper Planing Prevents Piss Poor Performance.......
heres my old school Colt sporter, with some Magpul furniture tossed on. Have a form 1 pending and will get the barrel chopped to 10.5 in...anyone know if the receiver extension is different on the 9mms? That magpul stock was a tight fit on there, to the point it doesnt adjust easily..

Personally I would avoid Glock lowers, they are not designed for a sub gun and take a beating, would atleast want upgraded spring but Colt pattern mags are great and getting cheaper. Get Metalform or Brownells, don't waste your time on C Products.
Having broken a couple bolt catches, do not skimp on buffer either. Get a heavy (8.5oz) buffer and good spring system. Ultimately I would suggest just getting a Colt, building can be finicky in terms of finding a fcg that works (apart from standard 9mm hammer) and bolt compatibility. I really want to try the JP bolt and recoil system to quiet down the twang when shooting suppressed, but at $400+ it's not worth the change over. If i was starting, i would look into it further.
It will be heavy, but you can save some money and weight going the DDLES or Qtr Circle lowers as well.
what is your preferred barrel length for your ar9?
i'm not sure either to go 10.5" or 14.5" (like my M4)
i don't like the glock version because
a) the bolt does not stay open when empty
b) i don't want to mess around with my bolt carrier to make it work
Just get the 6951.... They work and there are still(at least as of a few years ago,) a handful of federal agencies using them.

Nothing wrong with using a quality magwell adapter in a standard AR lower either. I see a lot of people going for dedicated lowers but there simply not required.
The new Gear Head Works brace should be a nice addition for those with AR pistols
