ATI Outdoors Advanced Tech AR-15 Buffer Spring – Mil-Spec Replacement

The ATI Outdoors Advanced Tech AR-15 Buffer Spring is a mil-spec replacement component designed to restore reliable cycling in AR-15 pattern rifles. This spring works with the buffer assembly to control bolt carrier group travel, manage recoil impulse, and ensure consistent feeding and ejection. Replacing a worn or weakened buffer spring can eliminate cycling issues, reduce bolt bounce, and restore proper function to your rifle.

Manufactured from heat-treated spring steel with a corrosion-resistant finish, this buffer spring is a direct drop-in replacement requiring no gunsmithing or special tools. Standard AR-15 buffer springs typically have a service life of 5,000–10,000 rounds depending on use; replacing the spring during routine maintenance helps prevent malfunctions before they occur.
