FX Impact m4 Barrel kit

Slug to pellet liner for now. Will eventually be looking at caliber as well.

I have a liner just held off on the full kit because I didn't know how much I would be swapping back and forth.

Do you have a list of the parts needed?
If you aren't changing length life is simpler What caliber is it now and where would you be going possibly? The brass barrel adapter, a liner, a probe, magazine and moderator sized appropriately is the first ones I think of for my m3.

I need to know where you're starting, where you might want to go, and potential uses. Any advise I give is going to be based on experiences or I will say it's based on reading. I was going to bump mine up to 25 from 22 and decided against it after some consideration.

The full kit really keeps life simple by not changing barrel adapters off the barrel tube. But it's spendy.

It is a standard 600mm 22cal with a slug liner now. I have a pellet liner thats the same lenght I would like to put together as a kit for now.

Future I will possibly want to change it to a 25cal slugger 600mm and or a 500mm 22cal pellet setup.

If you want the changeover to be quick on 22 to 25 I think you need the barrel adapter and it may be easier to do a kit. As for staying 22 it's super ez (as you probably know) to just pop out the liner and swap it. Up until you go 500 mm and have to buy skinny moderators to clear your bottle or buy a smaller bottle potentially.

I toyed with the ideas of all these options and just tuned my 700mm 22 for heavy slugs and bought a dreamline compact in 25 to cover my bases.
