I am a noob and looking at building my first AR-15 instead of buying a complete rifle for the sake of saving money.
I have been doing research into upper and lower receivers and had a few questions:

If I purchase a complete upper and complete lower, what else would I need to complete the gun? (tools, kits, other parts, etc.)
I am leaning towards a complete DS Arms ZM4 A3 upper and a complete Spikes Tatical lower, any reviews/opinions on these manufacturers?

DSA Upper

Spikes Tactical Lower

Any advice or help is welcomed and appreciated.

With the upper selected looks like just a charging handle and a bolt carrier group.  You will probably end up replacing the trigger for smoother pull.

And would not be considered a "build"....but rather slapping together a lower/upper

Are the spikes tactical lowers known for having bad triggers?

I don't actually know that.  Usually though the stock triggers aren't the best.  My first AR rifle was a Daniel Defense and it had a really gritty trigger.  The ones that come in lower parts kits aren't that good.

Is that barrel even chrome lined?

Look into a higher quality upper.
The bolt and barrel are the heart and soul of the weapon.
Don't cheap out on those parts.

USGI type triggers are a crap shoot.
That smooth out the more you shoot them.

Any recommendations on a different upper? I like the MOE front guard and would prefer to buy an upper with that installed

here is another alternative that has more accessories included (BCG, charging handle, rear sight)

If you desire an A2 posted upper then check out BCM.

Aero has some good prices on free float uppers right now.

I apologize in advance if this is a stupid noob question...does a front post sight interfere with mounting/using a red dot sight?

Agree 100% if your gonna go cheap and reliable go PSA they have great deals...and dont be afraid of the models that are marked down for (I forgot the correct term) damage. It usually isnt that bad maybe a nick or something....still fully functional though.
