is specially designed as a "one on one" replacement regulator for your FX Impact , FX Impact X or FX crown.
Unfortunately the fixed limited space in the FX Impact and Crown action was not sufficient for our standard Huma-Air Regulator design, so we had to comply our design to the ratio's used by FX.
Nevertheless they have accomplished to make a great replacement regulator that will solve the issues of the factory regulator.
