LBE Unlimited ARBF308R Recoil Buffer for .308 Win Rifle Length AR-10 - Silver Aluminum

The LBE Unlimited ARBF308R is a rifle-length recoil buffer engineered for .308 Win AR-10 platform rifles. If you're running an AR-10, LR-308, or SR-25 build with a rifle buffer tube and fixed stock, this is a straightforward upgrade that requires zero gunsmithing—drop it in and you're done. Recoil buffers absorb and manage the carrier's rearward travel, reducing felt recoil and helping your rifle settle faster between shots, which matters whether you're dialing in a new load at the range or hunting at distance.

Built domestically from an aluminum body with internal steel weights, the ARBF308R weighs just 5.4 ounces and measures 5.285 inches in length. That compact, lightweight design keeps your rifle balanced and handling responsive without adding unnecessary bulk to your receiver extension. The silver aluminum finish is clean and durable, standing up to regular use in field and range conditions.

LBE Unlimited has built their reputation on no-nonsense, American-made AR components, and this buffer reflects that philosophy—solid engineering, made here, no frills. It's the kind of part that works quietly in the background, doing its job without drama. Whether you're tuning a precision .308 setup or refreshing an existing build, this recoil buffer is a reliable choice for shooters who value quality US manufacturing.
