Barrel liners

[hoof hearted]

Has anyone got an opinion on the FX liners?  I have seen all the YouTube videos but most seem to be from FX sponsored shooters so do I believe the hype?. Good, bad, indifferent?

How difficult would it be fitting one into a rapid and is it worth it?

easy enough job.i would say they are no better than a good standard barrel.
