Matt, a fellow member from GTA regulated his S510 a few months back with great results. Here is some of his data and modifications.
Re: AA S510 Reg Project
I have adjustment lock on high power , there is a little screw on a AAs510 which enables you to lock power adjustment in place.
I used the factory hammer spring and just shorten it one coil.
Did not modify any ports /passages did change valve spring to one a little stronger which came with RL regulator Robert sent me two different springs for this one weaker and one stronger than the one that came with gun.
Polished rail and hammer.
O PS regulator came set at 130 psi which in the end I set it at 150 psi which work out best for the FPS and shot count I wanted.
AA s510 now has polished rail and hammer One coil removed from hammer spring and a Robert Lane regulator.
