What is the best beginner airsoft gun you ask? According to Gunfather Milsim, just pick any S&T Gen 3 Gearbox... "This is a short section of the Live Q&A from 26DEC21. In it I discuss my son's first airsoft gun, a Cybergun M4 AEG Rifle w/ G3 Micro-Switch Gearbox. This video is geared towards the parents who have kids looking to get into airsoft and are not quite sure which gun to buy their kids. There are a variety of good options out there but IMO parents should focus on the durability of the gearbox. Thus I would recommend any entry level gun with the S&T G3 gearbox is a good choice."
