FYI, I just sold one of those and installed a Prometheus MS120 spring for the customer, it chrono'd an average of 427.1 fps with the MS120. It should wear in to the 415-420 fps range after a game or two. Out of the box, it shot a average of 461.2 fps. My GF76 (FN FNC) shot over 470fps out of the box.
