Hi there,

Got the ICS M4 a few weeks ago, and decided to game this weekend.

Everything was fine out of the box.

I swapped the spring with a ST105 by element.

I installed everything back and now the rifle doesn't seem to have power.

Any ideas? Missed steps?

I opened the rifle and the bottom gear box won't spin even with battery in.

Thanks in advance.
