First off I live in California:
I just got my first Lower, a Vulcan V-15 Pinned Mag. with Bushy LPK.
Is this a good Lower, be honest.  it looks very good, No Machine marks
or rough edges, Good finish.
I now need an Upper, I want Accuracy but cannot afford $600-$800
Is Model 1 or JT good companies with good Upper's. Under $500.00 is my budget.
I would like a Flat Top that is light but again Accuracy is a must, if it can't do MOA I don't want it.
Is there a differance between 5.56 Nato and .223 chamber diminsions.
Thanks in advance.

If you like it, and it operates correctly, then your good to go.

Im pretty partial to RRA, but I think what it really comes down to is you get what you pay for.  You could go over to EE (equipment exchange) and check out some new and used stuff.  Buy all the upper parts and put it together yourself (not that complicated).  You would need armorers tools though, if your going to mount your own barrel.  I hear stickman puts whole rifles together pretty darn cheep doing it that way.

Is there a differance between 5.56 Nato and .223 chamber diminsions.

Yes there is a difference, but wether you buy a 5.56, .223, or Wylde chanber, both types of rounds will fit.  The difference between .223 and 5.56 ammo is the size of the neck on the casings.

Now THAT depends on who you ask...  Most will tell you NOT to shoot 5.56 in a .223 because it CAN (not will, but can) cause a dangerous over-pressure situation in your rifle.

It's not hard to just buy 5.56 or Wylde these days and shoot both.

I agree that RRA is a good choice, but definitely NOT from RRA directly.  Buy from one of the board supporting dealers here.  Check the EE, there are several.  Dealer threads are yellow or gold.  

I have no experience with Model1, but have never had to give them a try because I always got such great deals from places like ADCO and Legal Transfers. (listed in alphabetical order)

My personal vote is NOT to try and assemble your own UPPER until after you've decided you're addicted and purchasing all the necessary tools are worth it to you.  Assembling LOWERS on the other hand requires no special tools, so I don't see why not.  Having said that, I do have all the tools, and I do build my own uppers now, but I didn't start that until after I'd bought and sold a half-dozen different Armalite uppers just to get one mid-length barrel I wanted.  It does save a LITTLE money building your own, but I won't use cheap or no-name parts, so I don't save a lot.  Where it really saves big is again, swapping and making mods to your existing uppers.  

P.S. - Welcome to ARFCOM!

jt if you're gonna go with a kit.

My Vulcan receiver is a very nice piece, from the same sub-contractor everybody else uses. However, the fixed magazine is/was a serious POS! Mine was actually a USA brand 20rd that had been cut off at ~10rds and had a floorplate tack welded on.
I cut that thing out of there and replaced it with a new Bushmaster 10rd mag.

Thanks for the replies guy's:
I'm slowly learning alot.
