i just took apart the gun and looked at the internals. according to the diagram i should have a cup seal spring then a cup seal star and a cup seal. i'm missing the cup seal star and i never took the gun apart before. also it seems that the cup seal pin should thread into the cup seal, is this correct? the pin does not thread into the cup seal if this is whats supposed to happen. could this be the cause of all my recocking problems?
