I don't mean the rotation of the RE since we'll assume the end plate it keeping it properly timed. I'm asking if the bore of the RE is aligned with the upper. If not, this would explain the wear he is seeing inside the RE.

can we see a picture of the S bend present in your sprinco spring? Where is the bend developing? Im not sure what you are noticing, visually, with the sprinco spring. I have several sprinco action springs that have a slight wave to them after firing just a few hundred rounds. A picture would be immeasurably helpful.
I have Sprinco springs in all of my AR's. I've never rally heard of this issue. I'd probably be contacting Sprinco directly to get some guidance.

An easy way to eyeball this is to:
remove BCG
remove buffer/spring
cock hammer
Then you can eyeball through the hole in the buffer tube and visually see if the barrel bore and extension are aligned. (with a light shining down bore and in through ejection port.
I have noticed when mixing uppers/lowers, that some combinations don't line up as well and there can be noticeably more drag when charging.
Same length when new.
The OP needs to update the group with his findings.
Is it possible the springco isn't designed to be compressed to A5 length?
