Slug Power V2 Kit For FX Impact by Huma-Air
1x Dual Hole V-2 Transfer Port and Pin Probe
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 and the 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. The set also contain our High Flow Pin Probe for maximum airflow behind the projectile
Two different types of hammerweights are included in the kit. We made 2 models of this hammerweights, one slightly heavier compared to the factory model hammerweigth and the second one is again some heavier as the other.
In our own test setup we gained about 30 to 40 fps more speed to our slugs without changing any other variables.
