This training book has been developed from the ground up for beginners who know little about Airsoft AEG technology. As part of our Airsoft Technology Self-Paced Training Series, this book gives an introduction to the L85 AEG architecture. The primary goal of this book is to explain the various technical concepts in very simple language. * We use the ICS L85 AEG for demonstration. We believe that this book and its support materials have everything you need for an informative, interesting, challenging and entertaining Airsoft educational experience.
