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. At 5.2 ounces, this rifle buffer is noticeably heavier than the roughly 3-ounce carbine buffer used in 16-inch direct-impingement carbines, and it’s built specifically to run in a fixed-length rifle buffer tube rather than a collapsible one. That added mass slows the bolt carrier group’s rearward travel to match the longer dwell time typical of rifle-length gas systems, which is why swapping tube lengths without also swapping to the matching buffer weight can leave a build running rough. It threads into a standard mil-spec rifle length buffer tube alongside a rifle buffer spring, giving Anderson’s buffer, spring, and tube the same factory-matched geometry a rifle-length A2 stock configuration expects.
