So i got my new kwa m4 cqb, and when i had the battery charged, and i went out to fire for the first time, semi auto didnt work. I was so mad. Full auto works great though. O yea, sometimes it will fire full on the semi setting. I called evike, and the said to return it a get a new one, so I think I will use it on full auto only for a war tommarow, then ship it back.
Also, I got my upgrades, and it took some serious modding to fit the g&p hop up into my jg m4, but i finally got it there. I had to shave some plastic away with a dremal, and also shave so metal away from the hop up chamber. But in the end it all worked out. at this point, i am to tired to disassemble and take pics.
By the way, I only shaved the exterior of the hop chamber so don't freak.
