[SGT_Blaster]

Hi guy

At my last game my Tm g36C start to not fire on full auto. In semi auto it fine, but when i switch my trigger to the full auto nothing happen my trigger move but no bbs go out. If i play a little bit with my selector switch i can sometime go to full auto.

What is the problem my mechbox is out of my gun but i dont know where to check,

thank
