Hi Giles,

Question please about what FX do to make a Sub-12fpe Impact different from a FAC one? Apart from just the settings there seems to be some fundamentals that are changed. I am upgrading mine to an FAC version but apart from the Power Plenum, d you know what they change in the gun?

Cheers
Trevor
Hi Trevor,

It's best you contact FX Distribution UK direct and ask, things have changed over time and serial numbers can give a track and trace to what model you have and what may need changing.

Retail Sales:
Phone: +44 01392 354854

I would phone - email can take time. They have a specialist and can advise.

I also have to be careful advising on a public forum how / what to upgrade to change a rifle.

Sportsman can give you the best idea.

Cheers

Also the slug power kit provides a softer spring for the valve adjuster , then the slug probe provides a few more FPS, and then get the huma-air transfer port for a another 10 to 40 FPS depending on the barrel.
