Huma Air High Flow Kit for FX Impact- .22
This kit includes the High Flow V2 Dual Hole Transfer Port, Slug and Pellet Probe and the barrel attachment. *FITS: FX Impact .22
The successor to the high flow dual hole transfer port; Huma Air has optimized and enlarged the air passage in this new version. The V-shaped transfer opening makes sure you will have the maximum and smoothest air passage area. The middle support bridge divides the transfer port into a dual hole port. This middle bridge makes sure the pellet or slug nose cannot fall into the enlarged transfer port hole, but will be guided smoothly by the middle bridge into the barrel.
This dual hole transfer port has much larger air passage area compared to the OEM port for maximum performance. The increasement varies by caliber. In combination with the Huma Air's High Flow Slug and Pellet Probe, you will be able to get even more power out of your FX Impact.

Please Read - Installation Notes:
- Towards the end of 2022, some FX barrel kits were equipped with a long brass transfer port combined with barrel attachment, made out of one piece. If your barrel kit is equipped with this version, please select our optional stainless steel barrel attachment to your order for a one on one replacement.
- FX uses a medium strength thread locker to fixate the transfer port to the barrel to prevent the barrel coming loose. We strongly advice you to use a thread locking adhesive like Loctite® 2400 also.
- Huma Air has modified the O-ring groove dimensions and made the notch of the transfer port to be compatible with both the newest rifles as well as the older versions from FX.
- Before tightening the grubscrew that holds the barrel in the breech, make sure the barrel is adjusted properly so the magazine slides in and out smoothly.
*Any modification done to the airflow of your rifle will affect the setup and performance, you may need to re-adjust the settings of your rifle again to get the best possible performance.
