I was going through some spare parts and came across a buffer spring (seems to be heavy duty) but it is 9 1/4" inch long and only has 25 coils. Of course it was in an open plastic sleeve with no writing on it so I have no idea where this came from. Any help would be super appreciated.

It’s like 1” too short.

Is it braided wire?  Some of those gouged the shit out of my buffer tube and I sent them back.  I think it was a local AZ manufacturer.  I have recently seen a major manufacturer making them, but I still wouldn't trust them.  

The local guys sent them in a square expansion tube.  No label.  The replacements look like normal, but stainless steel wire. Same guys.

It is not braided wire, but it does feel like its a heavy duty spring.

The carbine buffer spring is around thirty seven coils.

Does it have any colors painted on it?

Sounds like it might be a LuthAR  AR10 carbine buffer spring. I have two of them that match the coil count and close to the length you posted that I got from Brownell's. I know the picture on Brownell's web site and Luth's website shown a longer spring with more coils but if you read the description on Luth's website mentions the 25 coils and a length of 9.75". The ones I bought are 9.5 inches long. The wire is about .007" thicker in diameter than a normal AR spring.

I have another brand of AR10 carbine buffer spring and it has a different coil count and length, so all brands do not appear to be the same on that spring.

No, just a regular buffer spring.

Thank you for checking on that. I must have purchased it by accident as I have no .308's.
