HELP No Semi-Auto

[coltron]

Ya, my G&P m4 works perfectly on full-auto but when i change it to semi it will shoot once and then make a weird sound when i try to shoot again, now it wont even work at all, it makes a sound like the battery is almost dead. Anyone know why or if it is easy to fix?

This happened to my Echo 1 M4. Mine was the firing mechanism inside the gearbox. It happened to my AK but I just switch it to Auto and back to Semi and it seems to do the trick.

Yes that works some times when i switch it to full auto then go back to semi, it will work for a minute then go back to non-firing. It really annoys me when im doing a semi-only game...
