    Description

    CNC aluminium device which fills the space around the HopUp chamber. Holds weak front part of the gearbox and prevents against breaking. Even more! Keeps wracked gearbox in the position and allow to continue with playing. Improved design allows using on the most common M4 AEG brands, such as AimTop,Matrix, Classic Army, Dboys, A&K, SRC, P&J, A.P.S, G&P. Not suitable for two-piece hopup chambers.

    The Rocket M-Block is made of very light, but durable aluminium T6 with nice metallic red finish. If you install this device in front wiring AEG, you must route wiring around the chamber and around this MBlock. Our previous model or other brands have square corners which may cause wire damage and shortcut. As you can see, we had changed the route of the wirings and critical corners were rounded. In the video below, you can see how to install MBlock in M4 with the front wiring. Installation is now much easier and faster.
