Default Buffer spring making noise

Today I had my Colt 6920 socom at the range and every time I fired I could hear the buffer spring making a "boing" noise as it cycled back & forth. Is this normal? I tend to think its not, since none of my other AR's make that sound. I think it could benefit from a little grease on the buffer spring, what do you guys think. Maybe some shooters with a little more experience could chime in? Thanks

They all do that to some degree. Its totally normal. Its one of the things I love best about it as it makes a very distinctive sound when firing at the enemy...

Some stocks transmit the sound better than others. Spend anytime with an a2 rifle stock and you can tell by the sound and feel if the gun is running right. I like the feedback as its an instant cue if something is wrong.

It's also instant feedback for when you fire that last round.

I agree it is normal. You can add a bit of lube to the spring, but be careful you do not over do it as any lube will attract dust/grit/fouling. Take a shotgun swab to the tube when you clean the gun, wipe down the spring and reapply the lube

With my limited ar knowledge I think I can say changing bolts from the lighter bolts to a m16 both slows the cycle speed a little and changes the spring sound. Changing to a lighter or heavier buffers will take that one step farther , maybe to the point its not noticeable to most

EXILE MACHINE TWANG DANG SWEET RECOIL SOUND AMPLIFIER
$179.99
AR-15 Buffer replacement amplifies the twang for our customers who can't get enough of the sweet sound of the recoil spring Twang.
Just replace your existing buffer with the TWANG DANG, and you will experience an 85dbA increase in twang sound pressure level (SPL). (Dang! it's loud!)
The sound is transmitted directly to your bluetooth-enabled electronic muffs (or similarly-enabled hearing aids) via bluetooth wireless connection.
For customers who do not use electronic muffs or hearing aids, we have an optional bluetooth cassette tape boombox adapter so you can set your boombox on your bench so everyone else can hear the amplified twang too.
The TWANG DANG is also perfectly matched to our ROKK STOKK 300W STEREO amplified A2 stock.
In live fire tests of our prototypes, we found a marked improvement in the ability of the shooter to hear the twang.
(Use of boombox not recommended at a public range. Nearby shooters may confuse your amplified twang with the unamplified twang of their own weapons.)

I already have an M-16 BCG in there. The spring & buffer are standard from Colt. And the buffer tube is only 4 position adjustable. I'm considering upgrading it to Spikes Tactical buffer & spring (I have very good experience with that one in my 1st build.) And I'll get a Magpul STR stock for it.

I always hang the action spring up and give it a good spray of lithium grease and that seems to dampen the boing some. Before I put together my 1st lower I read the book "The AR-15 Complete Assembly Guide" by Walt Kuleck with Clint McKee and they said "If you liberally grease (using Tetra Grease or a similar modern hi-tech, hi-temp grease) the buffer spring before you insert it, you will greatly reduce the boing sound caused by the buffer spring on cycling.)
