    like this one?

    I am asking this question, because I saw from youtube that the rifling is OUTSIDE in the barrel:) 

    why FX said it’s cost effective to make it?

    On the smooth twist and the x barrel the outside of the barrel has a “rifled” grove pressed into it which imparts a internal “rifled” ridge on the inside of the barrel.

    I would imagine that pressing in the rifling from outside is not only much quicker but also avoids the need for expensive machining/ drilling bits that need periodic replacement due to becoming dull. I would also imagine that it is cost effective due to less material being required to make the thin barrel liners. The actual process and machine is a trade secret.

    If I had to guess I think their secret process is just sending a heated tube through a die that rotates at a slow varying speed

    It also doesn’t impart nearly as significant wind catching impressions on the pellet which will aid in reducing wind drift. The design is accurate and easy to keep clean and accurate as it is smoother inside of the barrel. The design lends itself very well for airgun barrels.

    if a barrel can be pressed to create rifling from outside, then the material of the barrel should be very soft. Can a soft barrel last as long as traditional barrel?

    Can you show me a picture of inside the  smooth twist barrel?

    
Why firearm industry didn’t do it that way? is it because airgun pellet is  very soft?
