AR-15 Buffer Springs: Upgrade Your Recoil System for Reliability and Control
Your AR-15’s buffer spring plays a key role in how reliably your rifle cycles and how it feels during recoil. If you’re experiencing inconsistent performance or simply building a new AR-15, upgrading your buffer spring is an easy way to improve reliability and shooting comfort.
At Mounts Plus, we offer AR-15 buffer springs for both carbine and rifle-length systems, including standard mil-spec replacements, heavy-duty springs, and advanced captured recoil systems.

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.
