AR-15 Buffer Springs – Carbine & Rifle-Length Recoil Springs

Q: How often should I replace my AR-15 buffer spring?

Most AR-15 buffer springs should be replaced after 5,000 to 10,000 rounds, or sooner if you experience cycling or reliability issues.

Q: Are flat wire or braided buffer springs better than standard springs?

Flat wire and braided buffer springs can reduce felt recoil and improve durability under heavy use compared to standard mil-spec springs.

FAQ:

Q: What’s the difference between carbine and rifle-length buffer springs?
A: Carbine buffer springs are shorter and designed for carbine-length buffer tubes, while rifle-length springs are longer and only work in rifle-length tubes. Using the wrong size can cause cycling issues.

Q: How often should I replace my AR-15 buffer spring?
A: It depends on use. Most shooters replace buffer springs after 5,000–10,000 rounds, or sooner if experiencing reliability problems.

Q: Are flat wire or braided buffer springs better than standard springs?
A: Flat wire and braided springs reduce recoil impulse and can last longer under heavy use. They’re a good choice for competition or duty rifles.
