Bob The Axeman talks about the Ares Airsoft Amoeba M4 Stubby AEG which has an electronic trigger in this Airsoft GI video... "Each ARES gun replicates the look and feel of their true life counterparts, incorporating original and innovative designs. The ARES Amoeba Stubby M4's compact design serves a great purpose in close quarter environments and the Electronic Trigger System improves trigger response so when seconds count, your BB's land first."
