    Lighter weight, better heat transfer.

    They're taking a pencil barrel and using the procedure shown in this video to add Titanium to it. Once the Ti is added they turn it back down to a medium contour. It's a pretty cool what they're doing, but they could be going a lot lighter than a pencil profile with the steel. I'd cut it down to just a liner, maybe .100" over bore/chamber diameter.

    There was another company making composite barrels similar to this, but they were using explosive welding to combine stellite liners with aluminum, titanium, or steel barrels.

    Why not a full titanium barrel?

    Because Titanium makes really, really horrible barrels.

    Here's a quote from McMillan when they tried it.

    I fail to see any advantage in this projectile but can relate a story
    that might give a little light on what could be expected.

    A few years ago when the light rifle craze started I built a complete
    rifle out of titanium. It was chambered for 308. I had to use a steel
    bolt to bring the rifle up to 5lbs. We tested it for accuracy with 10
    rounds which was OK and then I borescoped the barrel and found that most
    of the rifling and some of the bore was missing for the first 8 inches.
    We tried another 10 rounds and an other 8 inches shed the rifling.
    Titanium is the worst metal I know of to gall. The barrel was galling
    to the bullet jacket and was ripping it out with every round. You could
    picture a titanium bullet galling to the steel rifling and doing the
    same thing.

    Steel isn't the ultimate barrel material, but the few metals that could outperform it are prohibitively expensive. No one, not even the military, wants to pay thousands of dollars for a single AR barrel.

    Could you chrome line it? Wouldn't think it would make much difference what metal is under the chrome lining.

    From what I understand Titanium has some other properties that make it less than ideal, even if it was chrome lined. Supposedly it like to return to its original shape when heated. It also loses strength rapidly when subjected to elevated temps.

    Don't know that, I'm not very well read on metal properties or very much else.
