The Geissele Automatics Premium Buffer Tube Assembly (brand part no. 08-163B-H3) pairs a mil-spec-diameter buffer tube with Geissele’s braided Super 42 buffer spring and an H3 buffer, finished in black. The Super 42 spring is built to reduce the buzzy vibration of a standard buffer spring, and the H3 buffer adds tungsten weight for a heavier, softer-cycling impulse.
