The Geissele Super 42 Buffer Spring and Buffer Combo utilizes a three-strand braided wire design to act as a harmonic damper and energy absorber. This design aims to displace excess energy, reduce spring failure, improve reliability, and decrease operational 'twang'. It offers increased strength and a 15% stronger return force compared to standard springs. However, it is explicitly not recommended for use with 300 Blackout ammunition.
