I'm new to the AR world and I had a question that I was hoping could be answered.  When shooting my new AR yesterday I noticed that I could really hear the buffer spring as it was operating and was wondering if this was normal.  Thanks for the help.

"Sproing".
Normal.

Yes. It's called the 'Sproing'. Listen carefully and you'll notice a difference in the sound when the bolt locks back on an empty mag. You can reduce the noise a little by lightly greasing the recoil spring. The 'sproing' is louder in a rifle buffer tube than it is a carbine.

A little lithium grease will calm it down...just rub some on the spring...

Aside from adding a little lube, chrome silicon springs (like Sprinco) also seem to be a little quieter.

Go and shoot a magazine through it without any hearing protection...
You'll never notice the spring sound again.

Normal, the vibrations from the spring rubbing the receiver extension transfer to your bones andyour mind turns that to sound.

No kidding!  My rifle really barks!    I had some decent plugs in yesterday and only put around 100 rounds through it but my right ear is still ringing a little bit today.  I thought my Norma 308 mag was loud!    I might have to spend a little on better plugs.  Thanks for the advice on greasing the spring.
