The buffer is the weighted component that rides inside the buffer tube and absorbs the rearward energy of the bolt carrier group as it travels back after each shot. Buffer weight directly affects how quickly the bolt carrier group cycles rearward, and matching the correct buffer weight to your gas system, barrel length, and ammunition selection is important for reliable and consistent operation. A standard mil-spec carbine buffer weighs approximately 3 ounces and is the baseline for most 16-inch carbine-length direct impingement AR-15 builds running standard mil-spec ammunition. A rifle-length buffer is longer and heavier, designed specifically for rifle-length buffer tubes and fixed stock configurations. If your AR-15 shows signs of overgassing — felt recoil spike, ejection at 3 to 4 o’clock, or accelerated carrier wear — increasing buffer weight is one of the first low-cost adjustments to try. Anderson Manufacturing buffers are machined to mil-spec dimensions and work with standard mil-spec bolt carrier groups and buffer springs in their respective tube lengths. For builders completing a new lower or replacing a worn buffer, the Anderson Manufacturing buffer is a direct-fit mil-spec replacement that restores factory buffer geometry and weight for standard function.
