I have an A2 stock with rifle length gas tube and appropriate buffer. Each round fired results in a nice "sproing" sound from the spring. How can I eliminate this annoying sound? All my other AR's are mid length or carbine and I don't get it from them. Would heavy grease be the answer?

| I thought the same thing after a build and jsut asked someone around me that had one. I thought it was odd but after the first time you shoot it you'll ignore it. At least I think I have. It lets you know the rifle is working and if you DON'T hear it you know something is up. |

Out of mere curiousity, why does this sproing noise bother such a fair amount of shooters? I can't say that in all my years of shooting this weapons system that I have even recognized it. I think its just that many of us who learned to shoot on other guns, got use to the nice solid feel of a bolt gun, or an M1 or M14. We just aren't use to the sproing. I have found the best way to get used to it is to shoot your AR....a lot. |

You can reduce it some by taking out the buffer retainer and the retainer spring.
Then the buffer will apply constant pressure against the back of the bolt carrier, you just have to open it slowly when you take it appart. This eliminates the carrier hitting the buffer, it just pushes it back without smacking into it. This is the method that CavArms recommends on their lowers. |

The only thing she likes about the AR;s are the two stage triggers. 458 |

This may be the case with Cav Arms lowers, but this isn't right for a standard forged lower. If you carefully close your your upper, you will notice the bolt carrier will slightly push the buffer back a little. If the bolt carrier doesn't do this, and the buffer impacted the retainer every time the rifle cycles, it will chew up the face of the buffer. I've seen this in several pics in different threads here. The buffer retainer is designed to retain the buffer when the rifle is opened. When the rifle is closed, the buffer doesn't touch the retainer. |

So stayed on the sound part. Thanks 458 |

Shooting carbines the last 9 years I wondered the same thing. I recently sent some rounds down range with a friends 20" A2 and it all came flooding back....it was like "music to my ears". The noise must be directly attributed to the Rifle buffer and action spring in the A2 stock because I don't notice anything remotely close in a collapsible stock. I use Tetra grease on all of my buffers and actions springs. Slather some on, it def won't hurt anything or make the noise worse. |

David Tubb CS Flat Wire Spring http://www.davidtubb.com/tcom_images/ar15_images/cs_buffer.html this will work with a rifle or carbine buffer tube. mine has been 100% reliable for 2-3k rounds. BCM middy, rifle buffer/tube. |

I'm not a fan of the sproing either. You can eliminate it by greasing it. I use Super Lube which is essentially food grade axle grease and doesn't have an odor. Just pull the spring out, glob some on and work the spring like an accordion to thoroughly coat. For purist operators, this is a no no; but for the casual plinker, the grease migration to the fire control group is of little issue. Just clean it out occasionally, no biggie.
I am a fan of the Tubb spring and I grease it, too. |

Also PanicBuyer said " I notice it a lot more when I rest my ear protection (muffs) on the stock. When I wear just ear plugs I don't notice it as much or at all." I just realized why the sproing is so loud to me. I'm shooting this rifle with an SWR suppressor on it. I wanted an AR I could hunt with and not have to wear the muffs. After I put it together but before I had the can on it, I shot it with muffs and didn't notice it at the time. Thanks again folks. |
