NightHawkInLight shows how to convert a leaf blower into a high capacity cheeseball machine gun. It is basically an airgun using similar concepts from Paintball and Nerf.

His cheeseball hopper/magazine reminds me of the RSCB magazine (clip) used in custom Nerf guns. Although the RSCB magazine only works on semi auto and not full auto.

I wonder if he used a paintball hopper if he could get a more reliable feeding system and increase his rate of fire?
