Wow these results were not what I expected from the hpa 1100 psi and 850 psi, I believe its from the short barrel and small ball diameter, i mean its only 3 inches long, I'm gonna add a longer barrel with the 8.5 gram steel balls and this should be a big increase or there is another restrictor hidden inside, I'm gonna fully open her up to have a look. i got 14 joules with co2 and 21 with hpa, i believe its around 7 joules out of the box, in this video i removed the valve block, you can see in my last video
