Jp tuned and polished buffer spring - JP Enterprises Tuned And Polished Buffer Spring

First off my old spring is still working fine and I will most likely be switching back to my old spring. I have read that this spring might rust, don't know for sure. I do know that it didn't really change anything as far as recoil or reliability to my gun and the main reason I purchased this was to get rid of the sprung sound my gun tends to make which seems louder then my carbine style ones. Even my brother who owns 7 AR15 things its loud and this spring didn't do anything to mitigate this sound. Spring maybe good overall, but I can't tell it's any different from my old spring made from stainless steel. JP generally doesn't disappoint and I am sure this is a good spring, but I wish I didn't waste my money on this.
