Upper receiver choices

[pilon]

Hello

This lower has Aero Precision, V Seven, BCM, and Geissele parts.

I have a CC BCG and charge handle ready.

Is this BCG compatible with Daniel Defence, or Bravo company upper or should I stick with my original plan to purchase a Colt Canada MRR upper when I can find (buy) one?
In other words is my CC BCG better mated to a CC receiver?

Darn newbie question I know but grateful for any advice.

Here's what I have to work with. It can be topped with either a 2-8 X 32 Nikon or a 1.5-4 X 32 Leopold.

Yes they're compatible. All AR parts that are made by reputable manufacturers are entirely interchangeable.
There's no "better" fit when interchanging brands, but I personally have a preference to use matching uppers and lowers. It's just a weird thing I do.

Buy which ever upper you want or can find and rest easy knowing they'll work together just fine.

Like FoxAlpha said, they're all compatible (unless you get into Uppers/Barrel combos that do not have M4 feed ramps in my experience)

The biggest problem I had with different uppers/lowers is the colour matching. The first AR I bought was an Eagle Arms; the upper and lower don't even match in colour/finish from the factory. It drives me nuts; but it still shoots the same as any other AR of similar quality. Just grab an upper that has the features you want; M4 feed ramps, slick side uppers (no forward assist or dust cover); or just buy the cheapest option if you've got low budget in mind. I'm currently a fan of Aero uppers and lowers because of the price point, but a $500 will seldom shoot better; it just may have better looks or additional options with it.

Yup!
