SRC XM8 feeding problem.
 

I got a SRC XM8(SDXR8) that I'm having feeding issue with. The gearbox and hop up is in excellent condition. I have tried a couple different brand mag and still does not feed except when I hold it up side down it will fire a round or two but is very weak. I tried my mags in my friend's gun and they work perfectly, I have tried everything I could but no luck I need some help with this one. Please.

Would a gear selector clip solve the problem?

Problem solved!
