Airsoft AEG Ultra FPS & ROF

To achieve ultra high FPS, you need to make sure the entire mechbox mechanism is optimized in such a way that the desired FPS can be produced without sacrificing ROF and battery life. That means you need to use techniques to reduce the friction introduced due to fast movement, to ensure the spring can rebound fast enough after compression, and to reduce the overall workload of the gears and the motor. The primary goal of this guide is to help you improve FPS and ROF in a cost effective way. Different mechbox modification techniques are covered. The focus of this title is the ARES T21 mechbox.
