Prometheus barrels fit perfectly with Mad Bull hop ups... that's what I have in my M16, but you need a thinner hop up rubber. I am currently using a Prometheus barrel + older guarder clear (back when they were good quality) + Mad Bull hop up unit. Works perfectly fine, but when I tried to fit a Modify hop up rubber in there, it didn't fit because of the extra ribs they added to the rubber to improve air seal.

YMMV, but it works very well for me. The air seal is amazing thanks to the very tight fit.
