I've been using a echo1 mp5k pdw as a primary at a few games for the summer and I've found it to be amazing.
I use it like a full auto pistol and being able to move it around without stock or bulk is a big advantage.
The accuracy isn's what my big mp5 is but in bursts it sprays a perfect area.
At 350 fps with an intellec 1400mah battery, this is quickly becoming my weapon of choice.
I want another. 2 of these things would be wild.
