I seem to remember reading somewhere (I can't recall where) that putting grease inside the buffer tube will quiet the spring sound. Does anyone have any experience with this method? If so, what kind of grease and how much is required? Has anyone successfully tried any alternate methods? TIA...JJ |
| I use a high grade automotive grease. It doesn't take much. Put a pinch between the tips of your thumb and forefinger and run it along the spring coil. If you are in really dusty/dirty conditions, you may want to forget the grease and live with the SPOOIINGGGG! |

While the "music" of the sproiinngg is in the ear of the beholder I find it annoying and cheap sounding. I contrast that sound to the different, more solid sound the rifle makes when the last round has been fired. The bolt stays back and there is no sproiinngg sound...just a short final blast with no toy-like "overtones." How do others feel and who tries to silence their spring? |
| My Armalite AR-A2 doesnt make that sound and never has. I have always made sure the spring was oiled since I bought it new and lots of oil was in it from Armalite upon receipt. Glad to know why they did so as I wouldnt like the sound I have heard on others. I just use gun oil. |

From the new Sinclair International catalog: Tubbs Speedlock AR-15 Buffer Spring "The new Speedlock AR-15 Buffer Spring is designed to reduce the pulse and overrun (that annoying "boing" or "twang") from your rifle, producing a smoother recoil cycle with less rifle movement. This spring is designed by 8-time national highpower champion David Tubb and carries the guaranteed 9002 quality control standards approval. Its precise construction is unaffected by rapid fire heat and enhances the function improving life of the part. The spring has been duty rated for 500,000 cycles, which will function consistently for the life of your rifle. Designed for AR-15 use only." Catalog # 14-5200 Speedlock AR-15 Buffer Spring $22.50 This was on page 89 of their 2002-A catalog and is probably available on their website as well. I just lube mine with Break Free and ignore the noise. |

This should be the link to the Tubbs Speedlock AR15 buffer spring. www.sinclairintl.com/cgi-bin/category.cgi?category=search&item=14-5200&type=store I dunno. I guess I'll stick with the spring that's in there. It works well and, to tell you the truth, I don't really notice the "sproing." Well, except for when it isn't there. And then I'm reaching for a new magazine.

Hmmm...ever since I got my postban (Colt Match Target), I've wondered about that "sproing". And though everyone I've ever let shoot it hands it back to me with that shit-eatin' grin on their face, almost everyone asks me about the noise. I've telling them it must have been designed that way.  However, I would like to try it out without the noise. VERY useful info on this post. Thanks!

| My friend (Deadeye47) has a Bushmaster 16" and it makes a very noticeable sproing where as my Colt preban 20" does not. Both shoot well so neither of us are complaining. But the first time I heard his do it it did catch my attention right away as I never heard it in over a decade of shooting in the military. |
LotBoy....I have a patent on a "Clip-On Brass Deflector Protector", only $5.00 each. Protects that AR15 brass deflector from the brass marks of ejected shells. Just pop it off and your brass defector is like new! LOL!! I just had too! |
I've seen a guy selling buffer springs at a gunshow that were dipped in plastic. The kind of stuff that you would use to put a new grip on pliers. I think its called "plastadip" or something like that. He swore up and down that it eliminates the rattle noise and doesn't effect function. I figured screw it, If it ain't broke don't fix it. I'll guess I just wait for the Teflon coated "tactical" version  that someone will eventually feel it necessary produce. JerrY |
OK, I tried the grease thing on my Colt. Before I went shooting this past Sunday (4/27) I gave the buffer a generous coating of high-temp bearing grease (Valvoline). It works. Really quiets down the spring. Shot about 20 rounds, broke it open to wipe away any excess before it got to the carrier. There was only a bit that worked it's way out. After 100 rounds, no more seeped out of the buffer area. If the "sproing" DOES bother you, and you don't consider it "AR music" this method will work.
