ICS Thermold Mag Problem
 

So I put my mag into my M4 today, prewound. As I inserted it, it unwound itself...
So I rewound it and started firing, after around 15 or so shots, it unwound itself again, and the spring lost tension.
Now when I wind it, it doesn't click and won't feed out of the mag.

Any Ideas? I bought the mag about 2 months ago...

I got the same issue with my mag.

Took apart my Mag this morning. Apparently the spring that stops the coil from unwinding doesn't want to stay on the winding wheel and keeps sliding around... I'll try and get some pictures of it tomorrow. Anybody have any ideas on how to fix this?
