FAP Airsoft BB Auto Loader

Airsoft BB Auto Loader by Functional Airsoft Printing

This is a auto loader for airsoft AEG magazines. It has been tested with Stanag midcaps (including EPM1's), Shotgun shells and Evo mags.

Uses a push down to activate system. Pour a bottle of bb's into the hopper connect up a 11.1V lipo and filling you mid caps will be a joy.
Includes easy unloading spout for when you have finished your day and want to unload you mags back into the hopper.

As the magazine is filled the force of the motor will lift the magazine up. Apply pressure till motor activates when upward force is felt allow magazine to lift off.

DO NOT hold down too hard the motor has enough torque to over load and split your mags you have been warned.
