    Looking For a 16" Pencil/Ultralight Profile 6.5G Barrel?

    Any ideas?

    I've checked all the usual rack grade suspects, no joy. I suppose I could "contract" one out from one of the premium shops if necessary.

    Juat thought I'd ask here first.

    I've used the Odin Works 16" ultralite with great success. AA makes a liteweight 16" barrel and Faxon makes a 16" gunner I believe. All would be solid choices.

    BA makes a 16" Hanson as well..

    All mentioned barrels could produce 1 MOA with the right loads.

    Appreciate the thought and effort but they're all heavier than my 16" Faxon 223 Wylde pencil barrel (19 oz) that I'm trying match with a Grendel. Which is lighter than the Grendel 12.5 BA pistol build I just finished. Bummer!

    The Faxon Gunner is closer than the others but it's still 5.5 oz more at 24.5 oz. The Odin Ultralite, AA and BA Hanson (already have 2 BA's) are right around 26-27 oz.

    The Faxon Gunner may indeed be the best "value", ounce for ounce though. Might be worth eating those 5.5 oz vs several hundred dollars more for a custom profile premium barrel. Of course, if they can guarantee 1/2" moa............

    Someone...anyone...correct my perception if I'm wrong about this: I THINK I read somewhere that a pencil barrel profile similar to those found on a .223 wouldn't be a good idea with a larger caliber projectile. Is my memory failing me?

    With an equivalent profile, the larger caliber barrel will be larger in diameter, requiring more steel and weighing more than a .223.
    A pencil barrel .223 can have a .625 gas block, but I don't recall seeing a Grendel with one.
    I think the Faxon Gunner is about as thin as they go.
    Maybe lose an oz or 2 by machining off half the Gunner's gas block journal...?

    I think your right, the .750 gas block diameter may be the minimum for the 6.5.

    I'd call McGowen and talk to someone there about how thin they'd make it. They have very reasonable prices for full custom barrels.

    LOL! I stand corrected! Still, I think Tex Nomex had it correct; I don't think I've ever seen a Grendel barrel offered with a .625 gas block diameter.

    Harpoon, I would not recommend a pencil thin for the Grrr. Barrel harmonics would be off. I have an AA bbl.- ultralite in SS. , 16" that shoots just fine.- also for sale-

    This is too fine of a caliber not to take advantage of all the work that went into it from the start. Bill A knows this round. hoop strength, etc. come to mind . Ask him, he's still with us here.

    Why do you want so thin?

    For the same reason they put thin barrels on the FAL and M14, too make it easier to "hump" around!

    Already have enough heavy rifles!
