This is an update to the Mag Fed Mini Rubber Band Gun. I have redesigned four parts to stop the back hook from jamming when pulling back the slide.

The parts changed are the Grip, Insert, Trigger and Back hook. All other parts are cross compatible.

This is the assembly video for the old version.

The only thing that has changed for assembly is that the trigger return spring (short spring) now sits between the Trigger and Insert (on top of the Trigger), instead of between the Grip and Trigger(below the Trigger).

 

 

 

 

I also recommend using metal for the back hook pin instead of filament. It wont ware out so quickly, I use coat hanger wire.

Springs I use (cut to length). https://www.mcmaster.com/9657K693/

Magnets I use. https://www.indigoinstruments.com/magnets/rare_earth/blocks/rare-earth-square-magnet-5x5x2.5mm-44222-2.5.html#8773
