Luth-AR Carbine Length Buffer Spring - AR-15 Compatible

Luth-AR Carbine Length Buffer Spring - AR-15 Compatible

Ensure consistent bolt cycling, reliable lockup, and smooth feeding in your AR-15 platform with the Luth-AR Carbine Buffer Spring. Engineered specifically for .223 Remington and 5.56 NATO rifles utilizing collapsible or fixed carbine-length receiver extensions, this high-tensile steel recoil spring provides the precise mechanical rate required to stripped rounds from the magazine and drive the bolt carrier group cleanly into battery.

Manufactured to strict OEM tolerances, the Luth-AR Carbine Action Spring is built from high-strength spring steel wire designed to withstand continuous compression cycles without taking a set or losing tension over time. Whether you are assembling a custom carbine lower, performing routine buffer system maintenance, or keeping an essential replacement spring in your field kit, this component ensures long-term operational reliability across duty, sport, and defensive applications.
