I was watching a review of a mid-length light weight PSA AR-15 on YT, and one of the things the reviewer mentioned is that he tends to replace the buffer spring on any lower price range AR in order to reduce the twangy sound affects.
Interestingly, the company he said he gets his “upgrade” spring from offers springs only for full-length and carbine-length applications.
He didn’t say which one he installed in his mid-length setup.
I’d love to hear from those of you who are knowledgeable as to what makes an “upgrade” spring quieter, and whether it’s critical to have a spring that is for mid-, carbine-, or full-length gas systems.
Thanks in advance for well considered advice.

They go in every one of my AR builds
It’s relatively low cost, and from the first round that you fire, you won’t regret the money that you spent on this upgrade
I have them in my AR9 direct blowback, 300 Blackout pistol, two 5.56 16”, and a 7.62x39 16”
No more “twang”. It’s silent

Springs are measured to buffer tubes, not length of gas system on barrel. So it depends on which tube you have (c tube, a2 tube, etc.). Buffers are measured the same. Longer for the fixed a2 atyle stocks which use a rifle length spring.

Try lubing the recoil spring first.
I’ve noticed as the mileage increases the recoil spring sound diminishes. I’d say money would be better spent on a legitimate 3 tungsten weight H3 buffer for lower priced builds.
Having a H3 (and the cheap carbine buffer that came with the lower) allows one to create four different buffer weights to see what works best.
