FX MK3 .35 compatible with MK1 barrels?

[Duanen]

Can anyone confirm that barrels from a MK1 is easily swapped to a M3? I see different answers and I'm sure I'm not the only one looking for this.

I have 3 barrels. .25 and two .30 All are pre x barrels and very accurate.. Is it a simple probe and barrel change, or is it more complicated?

I want to add a .35 and my MK1 won't do it.

I want one gun for all three calibers.

The barrels will definitely fit. Not 100% sure about the shrouds (possible interference with valve adjuster). But they can be changed if they don't.

if i remember correctly the pellet probe grub screw is larger from mk2 and later
