Tuning FX Impact Power Block and valve housing

[Seeker]

Here we go with the new valve housing:







No cutouts which should allow for better laminar flow of air.

I wonder how the Power Block could be modified. Any ideas?

Can be seen once a Power block gun comes to my hands. I hope that the block can be machined to accommodate the new valve housing. I feel that the valve of power block will also be bigger.

To me looks like that this system is more appropriate for 40 grain or above weight slugs in .22.

Or other very heavy slugs in .25 and bigger calibers.

As per my understanding, very large air passages becomes counter productive sometimes for light weight pellets. 

So we all need to see what we want.
