What Upper with a PSA lower?

[cobravenom39]

So I just got my PSA lower and was thinking about a matching upper.

I have it narrowed down to a DD, BCM or an Aero.

I can get the Aero for $79 assembled, but what about the finish? Is it close to the PSA lower?

I love the rear detent spring screw, though.

We tend to focus on more important issues than this.
