From the manufacturer

Low-friction Delrin disk fits on the end of the buffer spring, opposite the buffer, and stops the annoying "twang" of the buffer hitting the rear of the receiver extension during recoil. Quick, easy installation, with no permanent alterations to gun. Simply remove buffer and spring, insert Twang Buster, then reinstall buffer and spring. Mfg: Double Star SPECS: Machined Delrin thermoplastic, black. Fits A2 rifle and M4-style carbine buffer spring/receiver extension tubes.
