Well today I received an AR-15 billet set. I held the upper and lower together in my hands and could see daylight coming through the gap. I'm wondering if this is normal or should I send it back? I thought that they would mate together perfectly being that it is a matching set. Someone set me straight if I'm being a puss.

have you actually assembled the upper and lower yet? does the lower have the tension screw near the pistol grip? The fitment is really just for looks anyway but I would expect a matched set to be tight.
It might be better when its all together. If not, its your call on what to do. The gun will still function as it should.
I thought I did all my homework and asked for the opinions of the right people before purchasing. I guess I'm just going to see how well Mega stands behind their product. I was going to buy a nice AR from POF, Larue, JP or some other top shelf rig. However, I don't have 2-3K to spend on a rifle so as an alternative I bought a billet set that I thought would allow me to build up to something remarkable. It hurts to be told that I went with the wrong manufacturer.

my maten set is extremely high quality and a very tight fit. I am sure they will stand behind it. Receivers are receivers.. its what you put in them that makes the gun really shine.
Most every matched set of receivers will have a little light shine through. MY KAC and LMT guns are the same way as well as my matched mega sets. If the fit is tight in terms of wobble you are just fine. You have to remember these manufactured to be guns not parts on a jet or f1 car, the tolerances are not as tight.
When you actually put them together be sure to install the tension screw in the lower as it usually isn't installed from the factory. If it isn't tight after that call mega. I have two mega sets and both are flawless.
The fit on my MATEN MKM set is very tight, meaning no wobble whatsoever. Have not checked but I would not be surprised if I could see a little daylight between the two though. The light between the two wouldn't bother me as long as they were tight.
Mega has been quality for a while. I really like their upper and lower design. I liked them so much, I SBR'd one of their lowers.... great quality.
I will take your word for it and not worry about the light shining through. I handled a set at a LGS and realized the amount of wobble in mine is negligible. As soon as i get some pins in there the movement will be non existent. Now i just need to find a quality parts.
Ditto. My MKM set is very snug, very little play, but I can see daylight between them. Using a set of feeler gages, the gap is 0.005".
I have heard that a lot of the benchrest guys put bedding compound on their upper receivers to get that perfect snug fit to the lower, but come on... really?
Anyway, if the gap is ghastly, I'm sure Mega will make it right, but if it's just a tiny one like mine is, that's about as good as any mass produced receiver is going to be.
I don't think you went wrong going Mega. I love my Monolithic. My thought process was like yours, I dont want to spend 2-3K on a complete rifle, then you get all the parts you want for your build and you've got 2-3k in parts that you have to assemble. It's still fun to build one, and helps you understand your platform better, but almost never cheaper. Good Luck.
A homebrew rifle won't necessarily be cheaper right off the bat, but you'll save money on upgrades. Build it right the first time, with exactly the parts you want in it. I wanted an ambi safety, a Geissele trigger, an ergo grip, blah blah blah.
All told I spent close to $3K on my MATEN, but it started off in the exact configuration I wanted, vs. buying one from a brand name shop and swapping out bits and pieces.
Another plus was the learning experience, as bullseye13 said. You'll get to know the platform very well.
