So i would eliminate the orings on the drive first cant expect old orings that are worn to work the same on new parts.
Power tubes orings
If you replace these orings and still have an issue we will need a copy of the receipt when you bought the part so we can warrant the part for you.
You will need to send in the bolt in before we can send out a new part.
I replaced all of those o-rings and the gun was actually able to function with the gold bolt. However, the performance was far less then ideal; sound signature and consistency were considerably worse then stock. Efficiency seemed to be about the same... I purchased this bolt right off of MacDev's website approx 4 months ago... Let me know what you think.
