Prometheus 407mm to Mad Bull 509mm. Will i see a difference?
 

I'm about to sell my prometheus 407mm barrel and thinking about going with a Mad Bull 6.03 509mm Barrel. If I do I plan on also changing my cylinder, which is a type-2, to a type-0

Before I do this, I just wanted to know if I would see any noticeable(keyword) increase in performance(shot groupings, fps, range) from increasing the barrel length and from switching brands. Are the quality of Mad Bull equal to Prometheus? Thanks in advance
