Mini isn't shooting right

[Mobius V]

When I pull the trigger it fires and then when I let off, the sear goes half way to the fully cocked position fires then goes to the fully cocked position I oiled the on/off pin, replaced the all the on/off o-rings, the bolt isn't worn, as far as I know the sear isn't worn. Nothing should be worn I've only shot about 4-5 cases through it so the gun is fairly new... It doesn't make sense why it would be doing this unless there is something messed up on the inside where I can't get at it... I run nitro if that matters... Should I try buying a new sear and see if it works? Any assistance would be greatly appreciated.

Did you mess with your trigger pin? I did that by screwing it in so it would have a lighter trigger pull, and then it was doing the same thing yours was doing.
