I removed the back section of the gun behind the trigger using an allen wrench set.
I looked inside and noticed the white collar was cracked.
I removed the piece by pushing out from the outside of the gun where the air vents.
Ordered the replacement part.
Parts came and I reassembled from the diagram on the website .
The parts were listed in order so it wasn\'t rocket science.
