High flow, V2, dual hole transfer port with middle support bridge for FX Impact, FX Dreamline,  FX Wildcat MKIII and FX Crown.


The Latest Barrels from FX have done away with the Stainless Section between the Brass Transfer Port and Barrel making it all one piece. 

If wanting to use the Huma Dual Transfer port with a Barrel with this new Transfer Port Design you will need FX Barrel Attachment And Liner Lock Set as well. Any Questions Please contact me.


The successor to our high flow dual hole transferport;  we have managed to optimize and even enlarge the air passage in this new version 2 of our High Flow V2 Dual Hole Transferport. 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 transferport 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 perfomance.  The increasement varies by caliber:

In Combination with the Huma-Air High Flow Pellet/Slug Probe or Pin Probe for even more power from your FX.

 Please note:

FX uses a medium strength treadlocker to fixate the transferport to the barrel to prevent the barrel coming loose. We strongly advice you to use a treadlocking adhesive like Loctite® 2400 also.
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 posible performance.

Due the already huge increase of the airflow opening, the .177 dual hole model is not V-shaped
