I've built three AR's in the past...but always had the parts all together in a bag or something. I simply read the book and assembled.

Doing a build on a Noveske lower and the owner of the gun asked me WHICH DIAMETER buffer should she get...Mil-Spec or Commercial?

I had NO idea. Any advantage/disadvantage one over the other?  VLTOR Mod stock will be her stock of choice.

The buffer is the reciprocating weight.....don't worry about diameter with them.
The buffer tube or more correctly the receiver extension is what she is talking about.
Tell her to get a mil spec buffer tube (receiver extension) and the stock, of course will have to be mil spec to match.

Usually you can buy the entire kit and save a little cash.
Check DSG and/or Palmetto for the best deals on kits.

Any advantage over mil spec and commercial?

I don't see how there could be any realistic advantage one way or another.

Advantages with mil spec RE's...

More buttstock choices
Better fitment of stock (generally)
Threads are rolled in vs. cut = stronger part
Generally higher grade aluminum

It's best to avoid commercial unless you stumble upon a crazy good deal on a kit.

go with mil-spec. the commercial buffer tube has cut threads which isn't as strong and it has a slightly fatter dia so you have a very limited choice with stocks
