PROBLEM: My new m4 not working..... HELP!!!

[zollen]

I just received KWA M4S Tactical today. I put in the 8.4v 1600mah NiMh battery in the Rail compartment and put 10 bb bullets in the magazine. I switched the safety to semi, then squeezed the trigger. I heard shooting sound but nothing come out? Again I switched it to full auto, then squeezed the trigger, I heard a number of shooting sound but nothing came out. Occasionally, I did able to fire a few shots successfully (only a few) far between many empty shots. I turned the winding level under the magazine for a long while, it did not seems to help. The online retail offers only 48 hours return policy, so I need this to be resolved as soon as possible.

1. Would 10 bb bullets enough for the gun to fully functioning?
2. If not, how much bb bullets would I need to see some serious full-auto actions?
3. If I take out the magazine from the rifle, hold back the blocking switch (on top of the magazine) and then turn the winding level continuously, would bb bullets spill out from the magazine top hole?

High caps need MANY bbs to function. Try putting at least 100

1. No
2. 25-300
3. Yes, as you wind it, it should continuously feed BBs.

10 bbs probably won't feed properly using a Hi-Cap magazine (with the winding mechanism). You need to put more and you HAVE to wind it for it to work.

Buy some mid-caps if you are planning on fielding it. You don't need to wind them.
