Aea element .25 tuning

Just got my hands on the Aea element in .25. My question would be how have people been able to get more adjustment out of the hammer spring. I know I need to install a depinger. Because it has a horrible ping or twang from the spring. But I would like to be able to leave the transfer port all the way open and adjust throw the hammer spring. And also has anyone more baffles for the Aea rifles yet
