Geonox Airsoft goes over the MOSFET-equipped Specna Arms SA-E13 EDGE 2.0 AEG... "In this video we take a look at the Specna Arms SA-E13 Edge 2.0. It is a SAEG (Semi Automatic Electric Gun). It has 0.5 joules, has a semi (not a full auto) and is over 18. Inside we find an ETU (Electronic Trigger Unit) and a mosfet. The spring quick-change system is particularly simple, particularly fast and requires no tools. The innards are metal and airseal."
