Buffer Tube Spring Boing

Hey guys...so I have 2 CMMG ARs in Fiveseven. One has the shorter barrel and the other a little longer barrel. The shorter one has little to no spring boing when you shoot and the longer one has a decided spring boing as you shoot.

Should this be happening? What causes it? How do you stop it?

I don't have a technical answer, but I had a 5.56 AR with a spring like that. Bought a new spring... problem gone.

I would think that the buffer tube, buffer, brace, and spring would all be identical as they are the exact same gun but in different barrel lengths.

After a 1000 rounds it will go away

Spray on lithium grease, quiets it right out. Spray down the buffer spring with it (not dripping, just coated). Expect the excess to travel up the BCG, not far and easily wiped off.

Spring boing doesn't mean anything. It'll go away after awhile.

If you really don't like it, get a JP captured spring system.

Put a little grease inside your buffer tube. Fixed.

OR the Armaspec unit. The SRS-H2 i have works well, especially on my suppressed SBR.

I'm the odd one out I love the spring noise. It was the one thing that stood out to me as a little kid the first time I shot a ar15.

didn't they ban that noise in CA?
As it "may cause cancer" . Or was that diminished hearing? ;)

BTW: thanks for the info . My cousin is picking up a few kegs of powder for me .

Me too. Kinda' like the spring noise in a screen door. Easy to acoustically hear that bolt lock back on an empty mag.

Is the sound any different with a flat spring?

Sproing! [Flower]

The spring noise stood out to me as well.
That is why I ordered the JP Silent Captured Spring immediately.
Similar with the Kidd 10/22 bolt buffers to remove the 10/22 "bolt clack".

Those JP silent capture springs are nice. Everything JP is nice.

I have the Armaspec one. Works well

My Geisslle springs are quiet.

The rifle I had with the most spring noise was a ban era 20" Bushmaster, damn good rifle but you swore you had a pogo stick next to your ear when you shot it.

That?s funny. The one rifle I had that I really remember the spring sound to be a little excessive was also a 20? ban era Bushmaster.

Also, the simplest fix for those who don?t like the springy noise is to just shoot without hearing protection. I doubt you?d hear it then.

What?

I like the spring noise, reminds me that I’m shooting a rifle that was made by Mattel Toys.
