Reliable but loud - Aero Precision Enhanced Carbine Buffer Kit

I’ve put around 500 rounds on this now with a 12.5” and friends from 25 yards away say the sound of it cycling sounds like I’m shooting steal. The spring is extremely noisy when cycling, sounds like it scrapes the buffer tube the entire time. I had a basic carbine tube, spring and buffer from PSA in it before this and no problems, I’ll be switching it back and trashing this one. I reached out to Aero and have not heard anything back.
