Do springs matter......
Another newbie question on my first build.
I bought a Spikes ST-T2 and a biffer spring. The srping was cheap, talking $4 cheap. I recieved it and it is kind of rough. By that, I mean the spring itself is not smooth. The color is kind of brownish.
I know a spring is a spring, but is it?
A rough spring will be loud in the buffer tube I can tell you that much.
What kind of spring from Spikes? Or where did you order it?
Bravo Company. It was $4.50.
Should be good to go.
That's what I was thinking just going off of where I got it from. Not really going to hurt my pockets if it doesn't work out. That's the good thing.

No.
Rifle buffer springs are a different length than a Carbine Buffer Spring. 'Rifle' refers to stocks that use the full length receiver extension like for the A1/A2 fixed stocks, 'Carbine' springs are used in the Telestocks and other Short stocks (RRA Enrty/Bushmaster Stubber or the Sully Stock).
But as long as you buy they same type you're good to go.
I did get the carbine spring, so at least I got that part right :)
I would feel pretty confident with any product that Bravo Company carries.
If it is rough you might hit it with a light amount of lube to keep the noise of the spring in the buffer down if that bothers you.
Light sanding with 400 grit, then lube. I do this with mag springs, as well as the inside of the (aluminum) magazine. Instant break-in, super smooth.

JP propaganda....
JP Tuned and Polished Extra Power Buffer Spring - Carbine (for collapsible stocks)
JP has developed a new high grade extra power buffer spring for AR-15/M4 carbines with collapsible stocks. It is custom made to JP specifications. Center-less ground and polished to a mirror finish for silent, smooth operation. 7% more powerful spring rate for improved impulse feel resulting in faster sight recovery and improved reliability. This spring will make you AR-15 sound quieter and smoother. This is an inexpensive way to improve the sound, feel and reliability of your AR-15 or M4 carbine.
*Designed for .223/5.56mm rifles with collapsible stocks.
Features
Polished to a mirror finish for smooth, quiet operation
7% higher spring rate for faster cycling and improved reliability
Can't fault a guy for trying improve his own.
IIRC polishing spring steel is a Bad Idea, the steel will heat up & remove some of the springs memory & ability to rebound.

I have the BCM buffer spring. I compared the basic one that comes with the stocks and the BCM is stronger. you will hear the spring when shooting but you can CLP a little bit and may help, It will eventually go away the after some use.

If the action spring is made out of the correct material there is no danger of losing spring temper due to heat from polishing.
I bought a DD buffer tube and spring and the spring was rusty when I got it.

I took some oil and steel wool and cleaned the rust off of it. It has been GTG ever since.

Just shoot the thing and enjoy my friend. It will wear in and the roughness will go away. If it is loud just lube it lightly "NO SANDING" and go. It does not need to be dripping wet with oil save that for the bolt. My A2 stock rifle buffer is loud and it is just a smooth spring but it has gotten better as I have shot it. No worries though again.

This. I use 400-600 grit paper and then use Remington Dry Lube in the mag body. For recoil springs I use the same paper but use Mobil 1 axle grease to keep the sound down and for lube.
I have the same brownish spring (from bcm) and it had a lot of binding and stuff just from pulling the charging handle
I eventually did buy a replacement spring because of it, no type or amount of lube would get rid of the binding or noise
For whatever reason, buffer springs with rough coatings are pretty common now. They sound like sandpaper when you charge the weapon and just feel like they have a greater friction coefficient than typical buffer springs.
Thank you everyone for the support on this.
Still waiting on the LM tube extension to arive so I can continue my build.
The only innovative spring i know of is the Tubb Flat Wire spring. Make sense, and will hold it's spring rate for much longer than a cheap standard spring. Tubb spring is about $25 though.
I lightly coated the buffer and spring in my PSA mid-length with grease. No sproing noise.
