You can use any AR15 upper for your build. Just know that you will NOT have the "LRBO" option. Last Round Hold Open.

The only way to have that on a NFA lower is to wait for the NFA LRBO upper to come off back order.

Of course you need a 9mm caliber barrel, a specific 9mm ar bolt ( look for one ramped for a std AR hammer). If you are going to use glock magazines the bolt needs the Glock cut in it. You want the heaviest buffer and extra power spring. At least 6 oz up to preferably 8.5 oz.

Here is a good read on planning a 9mm build...
