The successor to Huma’s high flow dual hole transferport;  they 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 not 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 performance.  Varies by caliber:

Caliber  Surface Enlargement
.177 285 %
.22 176 %
.25 117 %
.30 122 %


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

Huma have modified the o-ring groove dimensions and and locating notch of the transferport to be compatible with both the newest rifles as well as the older versions from FX.
Before tightening the grub screw that holds the barrel in the breech, make sure the barrel is adjusted properly so the magazine slides in and out smoothly.
