2012 Airsoft Technology Self-Paced Training Series Assembling a long barrel M4 Airsoft AEG: Learn how to build a M4 airsoft AEG from ground zero! (Airsoft Technology Self-Paced Training 2012)

This new book is for intermediate level airsofters who want to assemble their own long barrel M4 AEG rifle from scratch. By building a new TM compatible M4 from ground zero you are free from those limitations imposed by the manufacturer default configuration. We show you how to use TM compatible metal body parts to build a very solid external for the gun. We then show you how to integrate an air-tight hopup system and high performance V2 gearbox to complete the build process. The configuration is optimized for a long barrel configuration where FPS and accuracy are of top priorities.
