Spartan Jess, The Halo Airsofting Spartan, shows you to build your own HALO Airsoft MA5B. You can use the APS Urban Assault Rifle (UAR) AEG as base fun for this project... "I made this video while creating my own Halo Airsoft MA5B, with the intent to show people how easy it is to create this conversion for themselves. If people can't afford to buy the super expensive and rare CB-88 (Airsoft MA5B) released by Evike, then you guys can  make your own Halo Airsoft MA5B with this tutorial."
