This High Flow V2 Dual Hole Transferport has a substantial larger air passage opening compared to the standard factory 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.

Best results are reached when combined with Huma's High Flow Slug- and Pellet Probe or the High Flow Pin Probe.
