Eventually they wear out, but I have a carbine buffer spring with around 9K rounds on it, and it still works great. Of course, I could replace it for under $10...

Would full-length rifle springs have a longer life expectancy than carbine-length springs?

It shouldn't. Springs wear out through compression and decompression, so i wouldn't think length would prolong the life of the spring. |

The action spring should never need replacement, but they're inexpensive and if a new one gives you that warm fuzzy feeling just do it

I keep a few spare rifle and car springs on hand, at $2 each, why not?
If you are going to shoot AR-15's, just lay in a supply of springs, pins, small parts. They are cheap, and better to have them on hand than have to order them. It is stupid to pay $6 or $6 shipping for one $2 part. Go on and get some stuff, oil them and store away. |

If a buffer spring wears out in two cases of ammo, it was defective to begin with.

buy a high quality buffer spring (LMT) and you'll never worry about it...

I have a registered M16 rifle and never had any problems with it until this weekend at a large get-together. Twice (out of hundreds of rounds) we had problems with it. After QuietShootr inspected it, the general consensus was that my buffer spring was too weak. BTW, I'm still using the factory A1 stock and buffer assembly, although the upper is a 14.5" M4. |

We had this discussion at TMO, the owners of older AR, think it was 15yrs & 17yrs, they said they never had to replaced their buffer spring.
I've got extra buffer springs,never had to changed one yet,but Im the type who always has parts on hand. TG |

The Tubb springs (ISMI) are stiffer than standard springs. Designed to keep the bolt locked slightly longer to improve accuracy. Keep in mind however that the intended use is on competition rifles that are heavily weighted and are shooting tpically heavier bullets with max-load powder charges (or close to it anyway). Just dropping one into a standard AR config may or may not work. The carbine spring under an H-buffer will commonly cause short stroking. Changing to a standard carbine buffer will often function okay though.
The Tubb springs are high quality and have their purpose, but they are not a cure all. |

I've got about 5000-6000 rounds on my old buffer spring and have never had a problem.

If that were true then they would be allowed to 'fail' and be replaced during the 6000 round acceptance test described in the Mil-Spec for the M16A2 rifle and M4 carbine. If the part was only expected to last 2500 rounds then it would require 2 changes for each of the 4 carbines during the test (total of 8 part changes). The spec only allows for 3 unservicable 'general' parts during the test (and those 'other parts' that are allowed failure are listed on page 12 and are limited to the fire control parts). If a buffer spring fails on ANY of the rifles or carbines then the acceptance test would fail - and the rifles would be rejected. It's all covered in Mil-C-70599A on page 11. Minimum expected life should be 6,000 rounds. |

Back when I was grunt in the USMC, my M16A1 was fed at least 8000 rounds, between blanks fired during MILES-equipped war-games, rifle re-qualification, and other "live fire exercises" of various kinds; I never experienced any short-stroking or other failures that could be attributed to the buffer spring.
I had one rifle assigned to me during those years, so I got to know it pretty well. I know that springs can and do wear out. I just don't think its something to worry overmuch about. Keep a spare in your range box, along with an extra extractor and other assorted goodies and you'll be set. |

I don't believe that's the way they're marketed. Their CWS is, but the spring is marketed more as a lifetime replacement part for a stock spring. They maintain stock springs will weaken and shorten over time to the point that malfunctions occur. They further maintain their chrome silicon springs won't lose compression or shorten over time. They also maintain that chrome silicon has certain properties which make them superior: can operate in high heat without degrading, and that they can use a lighter spring weight yet still provide full force when compressed. Not sure I'm convinced that their product is superior to others, but if it truly is a lifetime replacement, it would offer peace of mind. In the grand scheme of things, $25.00 isn't going to break the bank. |

Wolff offers a spring for only $15. It is extra power, but if the Tubb spring actually is stiffer, then the effect is the same and for less money. |
