I am trying to modify my 54 for FT competition use, so far the internals have been stripped, buttoned, new delrin spaces fitted to reduce volumes etc. Am now thinking of having a light weight piston manufactured also the transfer port size elarged am just wondering if any of you guys had tried doing this and to what effect?
Have heard of people reducing the volume by sleeveing the compression chamber and then reducing the diameter of the piston, would this be the way to go?
