Anyone run one without the velocity stack. I can save a inch it I don't use velocity stack. On my zenoah it ran just as good without them . Velocity stack only help a little with spitting. I guess I will find out when I run it.
That 1 inch farther out makes a big difference.
with a 3 inch standoff without velocity stack I can prime it still with my finger.
4 inch standoff with velocity stack is a little to far out.
3 inch standoffs ballance better.
