The Luth-Ar AR-308 Commercial Carbine Buffer Assembly is a direct-replacement bolt carrier group component designed for AR-platform rifles chambered in .308 Winchester. If you're running an AR-10 or other .308-based AR and need to restore or upgrade your buffer system, this assembly gives you a factory-spec part from a builder known for solid AR engineering. It's the kind of straightforward, no-nonsense component that lets you focus on the rifle's performance rather than worrying about whether the buffer is up to the job.
This is a commercial-profile buffer assembly, which means it's sized and weighted for standard AR-15-pattern receivers and stocks common in most modern builds. Whether you're assembling a new .308 rifle, replacing a worn buffer system, or swapping to a known-good OEM part, the Luth-Ar assembly is a reliable choice that won't surprise you with unexpected compatibility headaches.
Luth-Ar has built a solid reputation in the AR community for no-frills, accurate parts. This buffer assembly reflects that approach: it does one job and does it right, with the fit and function hunters, competitive shooters, and recreational builders expect from a factory replacement component.
This assembly is designed for AR-platform rifles chambered in .308 Winchester and fits standard AR-15 receivers with commercial-profile dimensions.
This is a buffer assembly—a direct factory replacement part for your rifle's buffer system.
