An entry level Classic Army AEG now with the ECS. Airsoft GI tells you more about the Classic Army ECS KM10... "Is this the most affordable and reliable entry-tier AEG yet? Very possibly! Mike takes a look at Classic Army's new line of Skirmish AEGs that come factory equipped with the ECS programmable trigger system! These badboys feature the snappiest trigger response we've ever seen from a stock AEG (let alone at this price level), and the ability to set the gun to 3 or 5 round burst!"
