Looking for a 9mm AR upper. Needs to be a flat top, and a low profile gas block is a plus. Any other parts are also a plus.

I can custom order them for you from CMMG. Unlike 5.56mm stuff, these are shipping within 1-2 weeks. Have both Pistol 7.3 versions and 16 inch versions available.

Pistol 9mm uppers are the bottom of this page (2 versions): http://tacticalcity.com/minorcategory.asp?CategoryID=1&SubCatID=43&MinorCatID=194&offset=-1

Carbine Lenth is here: http://tacticalcity.com/product_details.asp?ProdID=1309

Even though it does not say it, I think I can get them to customize it even further. I'll have to speak with my rep about it, and get a quote based on what you need.

Here is a link to magazine conversion blocks: http://tacticalcity.com/product_details.asp?ProdID=1353

I don't think they actually use a gas system at all. At least they do not on the pistol uppers. Which saved me money on my pistol build. No gas system, no gas block. The front sight is just there to be a sight. So without it, instant low profile for extended handguards. I do not know if this is true of the carbine length upper.

One nice feature is that these use standard AR15 triggers instead of 9mm triggers. So that helps save money.

At least with the Rock River Arms 9mm uppers, a 9mm specific hammer is needed in addition to the mag conversion block.

Thanks for that info!
