I can tell you this. I have a Palmer brass barrel, HPA tank, and Dead-On front bolt/power tube. Man is my marker spot on! I can literally put paint on paint in long consistent strings with this thing from 30-40' out. It’s rather quite remarkable. And this is while using a RT on full auto sweet spot mode while standing up! No prone or putting the gun in a vice either.
