AK47 problem

[hermy]

Hi I have a ak47 and the gun doesnt sound right when firing, the bbs roll out and some fire with no power, some miss fires and also seems to be air escaping from the gun underneath, any help would be greatly appreciated thanks

Firstly what make is it, try it with no hop, then slowly increase it, does just do this on semi, full auto or both, does sound same with no mag in, clean the inner barrel, if your able to take apart check hop rubber is not spilt, check air nossle for cracks
