[Turbo911]

Hi
I’m thinking of turning my impact sniper into a 3.5 slug slinger it is 2,5 cal at the moment can someone help me out with what parts are needed ie a barrel kit or do i have to order all the parts separately ie magazine slug probe etc ?

What you asking is a big jump with a powerstroke.
I did internal modifications on my own .25 MK2, wanted to jump from 35gr pellet into the 41-44 gr slug category, and if you not handy with some basic machining the power increase will cost you a lot more then you think.
This was my last winter project. The point is in un-restricting the air path = that is machining, + parts shipped from all over the globe (at that moment a year ago there was no single source where you can get it as a kit).
So I am talking now a jump from .25 pellets in 35gr 950 fps, and a jump to .25 slug in 44gr 1050 fps and 46gr 1000 fps with a Reg not reaching to 150 bar.

I believe the jump from .25 to .35 is feasable, many ways to do it, i would start with your local FX Rep what parts he has available or ETA.
But, back in time people did it quiet opposite, they started with a .35 Impact and did the upgrades towards smaller cal's.

I believe it is cheaper on total cost maybe getting a .35 cal and go from there.
I can recall reading about the brake point with FX Impacts was a .30 calibre. And from there you can "upgrade" either to lower calibres or higher calibres, but the parts will not support well both. The best would be talking to FX directly.
