A5 w/green Sprinco binding?

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.

"Concentricity" is the word I believe you are looking for.

Yes, thank you.

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.

But, wouldn't that be noticed with the normal spring as well?

Unless I am misinformed, are the standard and Sprinco springs different lengths?

[tehpwnag3]

Same length when new.

The OP needs to update the group with his findings.

I would think you would notice it with a normal spring too.. perhaps the extra spring pressure makes it noticeable?
Thicker wire?

Is it possible the springco isn't designed to be compressed to A5 length?
