The Skirmish ECS KM12 M4 is Classic Army’s entry level carbine. Utilizing Classic Army’s nylon fiber allows for a lighter weight platform while ensuring playable durability in a cost efficient package. The Skirmish ECS KM12 M4 features a high rate of fire along with a 300rd high capacity magazine so you can put more BBs on target faster than you can count. It also features a 12″ keymod rail system that has slots that you can use rail segments with to attach lights, lasers, bipod, forward grip, or anything else you may need. Front and rear flip up sights are included with plenty of rail space for you to mount a scope. It has a quicker change spring system so that you can quickly and easily upgrade or downgrade your spring once you remove the gearbox from the receiver.
Internally, the gun has a 9mm bushing gearbox, a brand-new electronic control system, inline mosfet protected trigger contacts, 6.03mm tightbore barrel, and a quicker change spring system. Program the electronic control system to shoot at 3 to 5 round burst. Additionally, the ECS has motor protection and low battery detection to help protect the airsoft gun in the long run. It will shoot 330-350 fps using 0.20g BBs and 900-1000 rpm using a 9.6V battery. This model comes with a three prong flash hider that has threads on it to attach a QD mock suppressor. Additionally, there is a flat trigger preinstalled that allows for a quicker trigger pull and response from the airsoft gun.
