DTW Airsoft goes over the features of the only double barreled M4 AEG in the market, the Classic Army DT4 AEG... "Classic army are the only airsoft company to release a double barreled M4 so of course i'm taking a look at it. This is the Classic army Nemesis DT4, the double barrel m4 that is a lot of fun to use but being a full metal construction you are basicly carrying two m4s at a time when you use this thing.

The DT4 also comes with a programible mosfet built inside the gearbox that can be programed off the  trigger, meaning no need to plug it into your phone or pc to change the settings."
