Yeah the spring in the box is the M100 spring. 300 FPS is not exactly what I was looking for, I thought it would shoot around 360 FPS with the M100 spring. Do you know how much an M120 spring would run? Would that boost the FPS ot 180 or would an M130 being required? What are some good quality springs? I did see a System M130 spring for $20 on Airsoft GI, would this be of good quality? Also, all the internals are metal (I believe) so would there be a need to replace the pistons, bushings or spring guide?

EDIT: Thanks hectic, I may just keep the barrel how it is for now. Good to know it's not to hard. I may watch a number of videos first before I attempt anything. Are you able to answer the above questions as well?
