This way, they will perform well in the field, and last longer so always make this a regular thing before or after going to an airsoft game. In this Airsoft GI Uncut episode, it is is about the cleaning and maintenance of AEG barrels as shown by Zach. In case you have forgotten, this should freshen your memory... "Zach from GI Tactical in VA shows you how to clean your inner barrel, both quickly and more in depth way to deeply clean it."
