    A 455-509mm Prometheus inner barrel, Prometheus hop-up chamber and the proper cylinder (type 0) would perform very well. You could also look into one of the popular hop-up mods such as an r-hop or flat hop for better performance.

    We need to know what gun you are using before I can tell you length, but a madbull 6.03 with systema bucking and stock hopup Chamber will perform well.
