Say i want to get a lower from one company but an upper from another. Automatic fit/functionality no matter what right?

I'm wanting to use a Spikes Tactical lower and put an Aeroprecision M4E1 one piece upper.

Using the term platform is misleading. AR15 and AR10 are two different platforms in which certain parts are not interchangeable (upper receiver, lower receiver, bolt, mags, etc.)

If you are referring to manufacturers, if they are reputable, they should produce mil-spec parts and should be interchangeable within the same platform. I.E. I use BCM uppers on PSA lowers with no fitment issues.

no issues.

I have a DPMS lower and an LMT upper one.

Another is DPMS lower and building one with a YHM upper receiver and various other manufacturers on the rest

Make sure everything is mil spec and you're good to go. Only problem I've ever had is when I used a Spikes lower-if you side by side with another manufacturer you'll notice that Spikes are a tad bit thinner. All other builds using Anderson and rock river parts no problems.
Armalite is a whole different story. They are different than everyone else.

After your edit:

In this instance, using Spikes and Aero, yes they will fit but there may be a little wiggle.

No matter what, no. Refer to my post above.

Let me restate my answer.

There are mil-spec lowers and commercial lowers

As far as i know the major difference is Mil-spec requires a smaller buffer tube.

it's their cnc forged Pirate. I don't want the billet because i've heard about issues with the fitment. People saying the billet will drop magazines.

That upper is the new M4E1 enhanced. It uses M4 feedramps and is one piece forged design.

I'm shooting for this look,with the Spikes lower.

There are milpec and commercial BUFFER TUBES...90% of lowers are made to the same milspec dimensions, but may not be milspec bc of different coating, metals, etc...

To answer OP's question..they will mate up fine.

Agreed. It caught my eye and as I scrolled down, your post nailed it.

It looks really cool whether it has some wiggle or not.

The upper and lower will not be one piece. This is where the "wiggle" would be. A little "wiggle" is not necessarily a bad thing on an AR and to an extent is expected. If your rifle/pistol has a little wiggle and you can't stand it then you can get an accuwedge or a lower that has a set screw that will make the fit tighter.
