Got a little busy, but finally got around to correcting the build. Here is the 99% solution. Magpul stock and grip, milspec buffer tube and carbine buffer spring (thanks Wolverine, fast work and John patiently answered my obvious questions). Besides additional mags, the only thing I want to add at this point is a vertforegrip and sling.
With the proper buffer spring and Magpul stock there is no rattle with the Spikes heavy buffer. Feels and sounds really good. Lesson learned.
I love the look and feel of this rig. Everything is positive and tight. The nose is a little heavy, but I like it. It is very quick to the shoulder and points well.
The Uzi mag needs to be modified, see my other thread

It just looks right and I want steel mags (that work).
I still have to get it to the range to see how it runs. That may be a little way off as I just found out we are moving to Grande Prairie at the end of the month. I have faith in the Spikes Tactical magblock that any adjustment required will be easy to do.
Some notes on the build:
1) I did not have a dedicated 9mm AR upper vice block. I found that in order to get the dust cover installed it had to go on before the barrel nut. So I cut out the top half of the vice block from the front of the 9mm deflector back in order to mate it to that side of the upper. Worked like a charm. It should still work fine for a standard AR or I'll just buy another set and call this one my 9mm AR vice block set.
2) This is my second total build and if you just take your time its no problem. Even the detent and springs went in easier this time (only shot one across the room once). I followed the build info at ARFdotCOM and Brownells AR video section.
Finally joined the 9mm AR club.
