Ernest's newest development for the FX Wildcat / FX Streamline plenum!
Mlre than double the length of the previous plenum (1.2" to 2.5"), and more effective than combining two together (no internal threading and less seals).
Allows the regulator adjustment hole to clear the Wildcat brackets.
With 1 of these, you can still add any size silencer to a .30cal Wildcat! All other calibers will need to use a smaller silencer such as a DonnyFL Tanto or Koi.
This also has a dual purpose of a tube extension, if you are looking for shot count rather than power!
Very limited quantity, buy one while they are here!
