On special request of many of our customers, we made a Pin Probe model for the FX Impact. In combination with our Dual Hole V2 Transfer Port you will gain more performance out of your FX Impact specially when you shoot slugs. Although this probe is specially developed for slugs we get a lot feedback from guys using it for pellets too.
Please note:
Any modification done to the airflow of your rifle, will affect the entire setup and performance, you might need to re-adjust the settings of your rifle again to get the best possible performance.
