The M block is a very useful component for absorbing vibrations and reducing the risk of gearbox breakage in the front part of the weapon. This component is positioned between the gearbox and the hop-up unit and serves the function of absorbing vibrations generated by the piston head when it strikes, allowing the pressure to be discharged onto the outer shell.
