AEG is an abbreviation for Automatic Electric Gun.
Have you charged your battery? :) Please make sure that you have charged you battery for the required time period. This required charging time for your battery depends on the capacity (stated in mAh) and the charging rate of your charger, which is normal stated in mA. For more information on how to calculate this, please see How long do I need to charge my battery?
First, we need to find out why your rifle isn’t firing BB’s.:
Are there BB’s jammed inside the barrel and have you attempted to clear it with a cleaning rod? Please refer to manual or check YouTube for tutorials on how to do this. ‘Airsoft barrel clearing’ and also ‘Airsoft barrel CLEANING’ is very important.
What brand and weight of BB’s were you using when it stopped? You must use high quality, perfectly smooth and round BB’s that are the correct weight specification for the Airsoft gun. Incorrect weight and quality are almost certain to jam and damage your gun.
Are you filling the magazine correctly? High cap mags need filled through the lidded hatch -NOT the round B.B. outlet hole- and are you winding the ratchet wheel on the mag base as you fire? You need to rewind the mag every 20-30 rounds to keep it feeding ammo into the gun. If your magazine does not have a ratchet wheel on the bottom, then it is likely to be a mid cap or low cap magazine and needs to be filled through the round B.B. outlet hole until the BB’s stop going in. A speed loader makes this task much easier!
In the meantime, please do not fire the rifle if it is blocked with BB’s as you will quite likely break the gearbox.
