FX Airguns FX Crown MKII STD GRS Green Mountain

FX Crown MKII STD GRS Green Mountain

The dramatic evolution of airguns has ramped up demands from shooters worldwide and we have seen an increased desire for more air flow and power in our air rifles. Whereas bullpup configurations can more easily add plenum space and valving for these demands, a traditional rifle like the FX Crown was limited for these demands… until now! The FX Crown MKII brings more power and even more capabilities to an already near perfect platform.

The increased power available in the MKII comes down to a combination of valving, porting, and plenum space. The plenum of the FX Crown MKII has increased 28% over the previous model! This larger plenum (the chamber of compressed air located before the transfer port) works in tandem with the porting and a new larger valve on the MKII (6.5mm valve). The combination provides spectacular results.
