Classic Rt leaking out the back

[Hellomynameisjose]

I recently dropped in a level ten bolt on my Classic RT which is working but when I bumped up the pressure it started leaking out the back where the velocity adjuster is at and idk why what should I do??

The original rt reg pistons were set to vent at a lower pressure than what is required for level 10. I would recommend picking up a new one from AGD.

Yes. Definitely replace the old lower pressure regulator piston assembly. Its a common problem when upgrading an older mag to a level 10 bolt that requires a higher chamber pressure.
