Instead of starting a new thread re: 9mm ARs I'll temporarily hijack this one hehe.
I picked up a stripped C-9 lower at NFA last week and am awaiting shipment/delivery of a lower parts kit with SB Tactical SBA3 pistol brace from PSA. My main reason in wanting a 9mm AR pistol is as a host for my still incarcerated AAC Ti-Rant 9M (today is day 139 woohoo). I'd debated SBRing my Scorpion Evo 3 carbine but having two Form 4s pending is enough hurry up and wait for me right now.
What barrel length should I be looking at for better accuracy but still keep heavier bullet weights subsonic? I have never shot 147gr ammo out of anything other than a Glock 19 so I'm unsure if longer barrels make 147gr go supersonic. For aesthetics I'd like to have a hand guard longer than the barrel so that the can is partially recessed in it (the can is 1.375" in diameter). I'm open to building or buying an upper if anyone knows of reasonably priced ones with an inside hand guard diameter that big. I like the ones NFA makes but that whole making it look purdy thing has ruled theirs out as the inside diameter of the hand guard is a tad too narrow.
Ar style 9mm are a ton of fun. No reason not to have one. Bought most of the parts from the fs forums here. Mines 4.5”barrel configured for glock mags.

Runs like a top with any ammo rnd nose or hp
I am collecting parts do build another 9mm AR, I like the looks of a 7 1/2"- 8 1/2" barrel, I got a deal on a Hahn mag well adapter [for $75 bucks + 2 mags!!!] I am going to use a 80% lower and what ever bolt and upper/float tube I can find. Its just going to be a shooter.
