I removed gun head and saw the problem. Removed piston with a 90 degree pic through center of piston. I then prepped new piston by installing new o-ring, piston spring, and lube. I then pressed piston assembly into gun head, installed gun head with four screws. Test fired worked perfect.

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.
