The Luth-AR Standard A2 AR-10 rifle buttstock buffer spring is a mil-spec replacement component built to restore or maintain reliable operation in your .308 platform rifle. Whether you're upgrading a worn-out stock assembly, building a new AR-10, or keeping a trusted rifle running strong, this buffer spring delivers the durability and precision you need for consistent, dependable performance at the range or in the field.
AR-10 owners know that the buffer system is critical to function—it manages recoil impulse, cycles the action reliably, and takes a beating over thousands of rounds. A worn or weak spring can lead to reliability issues that cascade through the whole rifle. Luth-AR's manufacturing standards prioritize long-term durability and exact mil-spec tolerances, so you're getting a replacement that performs like the original without the guesswork of off-spec components.
If you're refreshing an AR-10 stock assembly or simply stocking spare parts for your maintenance kit, this buffer spring is engineered for years of consistent service. It's the kind of component that works best when you never think about it—until you realize thousands of rounds later that it's still running flawlessly.
