Before i pull my gun apart just wondered if anyone has a clue as to why it constantly fires in safety / semi and auto only way to stop is remove battery.

trigger returns to its correct position correctly

Thanks

Probably the little spring that pulls back the part your trigger pushes has snapped.

Spring sets are pretty cheap though.

Bugger is that the inside spring ? or the spring on the outside selector plastic thing ?
