With respect to reloading, understand that the AEG feeder tube likely carries 2-3 BBs and that these need to stay there or drop out fully before loading a new mag. To preserve BBs, some players reload upside-down. In addition, if you are reloading right side up, a fast reload may not allow the 2-3 remaining BBs to drop fully and may jam by falling out partially but staying on top of the mag. The result is a mag that won't load, and potentially a BB that needs to be pried out with needlenose pliers or other motivator.
