Mk2 impact 25 changed to a 30

I want to try out a noe mold for pellets in 30 cal so I swapped out barrel to 600 mm from a 700 mm I removed the block and ported it and the valve and used a huma transfer port swapped out to a tungsten hammer I've also installed a 720 plenum on it the mold is dropping 51 gr pellets at 155 bar I'm running 920 fps with the valve control set just above 3rd line
