I haven't found anybody who has tried the Otis Life Liner ceramic barrel treatment yet.

If it isn't mouse milk, I'd like to treat the barrel of my K-31.

It sounds like snake oil to me.
Barrels go because when pressure exceeds 40K PSI, the temperature is high enough to melt steel. This is why the throat goes first, and eats forward(the pressure drops as the bullet moves up the barrel. You are literally blowtorching the throat of the barrel. What happens is cracks form, and eventually metal flakes off. Some competitive shooters extend their barrel life by using a reamer every 200-500 rounds, cleaning up the cracks(yes it still moves the throat forward, but not as fast as what it normally would - as fast as .007 per 100 rounds!)

Cryo is the only thing that works, and only so much.

What about chrome lined barrels?

I don't see Chrome lining to be too much of an advantage unless full auto is involved - and it has some major drawbacks - you can easily make a bad barrel worse, because Chrome plating has the annoying habit of amplifying defects - it doesn't "fill in", it puts an even layer of metal, which makes scratches, gouges, etc actually larger..
