Classic Army has updated its M16A1 AEG with its own ETU and Geonox Airsoft takes a look at it in this video review... "In this video I show you the M16A1 from Classic Army. This airsoft has an energy of 0.5J and is from 14. It is an old school, cult design, known from many films and video games, especially from Commando with Arnold Schwarzenegger, Rambo with Sylvester Stallone and of course from various Vietnam films.

We have a classic look here with modern internals. We have an ETU (Electronic Trigger Unit) here. It protects you from gearbox jams. You definitely don't want a Gearbox Jam on a game day. Then you pull the trigger and nothing happens anymore. The ETU protects you from this. And we have a mosfet here. The Mosfet protects the internals and gives the Airsoft a better, crisper response."
