Luth-AR .308 Rifle Buffer Spring – AR-10/LR-308 Pattern Rifles

The Luth-AR .308 Rifle Buffer Spring is engineered specifically for AR-10 and LR-308 pattern rifles, providing reliable cycling for larger-caliber semi-automatic platforms. This spring is designed to handle the increased bolt carrier mass and recoil impulse of .308 Winchester/7.62x51mm NATO rifles, replacing worn or underperforming factory springs that can cause cycling issues or premature wear on internal components.

Constructed from high-tensile spring steel with a durable finish, this buffer spring is a direct drop-in replacement requiring no gunsmithing or modifications. Installation takes minutes with basic disassembly of the buffer tube assembly. Upgrading to a fresh buffer spring restores proper timing and can resolve short-stroking, bolt bounce, or excessive felt recoil in .308 AR builds.
