Luth Ar 308 Rifle Buffer Spring

The Luth-AR 308 Rifle Buffer Spring is a precision-engineered recoil management component specifically designed for .308 Winchester caliber rifles and compatible large-frame AR-10 platforms. This buffer spring plays a crucial role in the bolt carrier group cycle, effectively absorbing and controlling recoil energy to enhance shooting performance.

Manufactured to Luth-AR's high standards, this buffer spring features precise tolerances that ensure reliable spring rates and consistent preload throughout its service life. Proper spring tension is vital for reliable feeding, extraction, and ejection, as undersprung systems can lead to short-stroking, while oversprung components may increase wear on internal parts.

This buffer spring is particularly beneficial for those building or upgrading .308 AR-10-pattern rifles, ensuring optimal cycling across various ammunition loads and barrel lengths. Whether replacing a worn spring or fine-tuning a new build, this component is foundational for reliable rifle performance.
