    HBAR Barrel Fluting?

    I was wondering if anyone has tried or considered having their XCR heavy barrel fluted?
    Any recommendations on who to send the barrel to for the fluting?
    Thanks in advance for your replies.

    That would a be nice touch. Any gunsmith with a machine shop could probably do it. The only problem would be matching the barrel finish. But seeing your art work, I don't think that would be a problem with you.

    Thanks man. I plan to finish the barrel in matte black after I get it fluted. The upper and furniture are OD green.

    I read today that the flutiong does not add any stiffenss, causes uneven heating and can affect the barrel harmonics due to the additional machining. I beleive that there were some issues that Robinson had with these in thier current production.

    anybody verify this?

    Fluting done wrong is a complete disaster. If it's done right, it can add stiffness, aid in heat dispersal, etc. If it's done wrong, then it will screw up the barrel's accuracy bigtime.

    I have two guns with a factory fluted barrel. One is a Blaser and shoots extremely well. The other is a Steyr Scout and it's shockingly accurate. I would NOT have a barrel aftermarket fluted. Those two guns just happened to have factory fluted barrels and you didn't have any choice in the matter. It's the only way they made them.

    Personally, I just as soon not have it. But that's just my opinion.

    Thanks every one for the input. I may leave the heavy barrel as is.

    You can check out the Gallery section of this forum, and you should see a selection of light and heavy barrels.

    This is my SBR XCR with heavy barrel: https://xcrforum.com/index.php/topic,330.0.html

    and others: https://xcrforum.com/index.php/topic,5.0.html

    Also, when I asked Chuck of RobArm the question of how much more does the heavy barreled version weigh over the light barreled version, he put both on the scales for me then and there. How's that for customer service: The results were:

    XCR light barrel = 7lb 4oz.
    XCR heavy barrel = 8lb 0oz.

    I hope this helps you with your question.
    O.S.O.K.

    Here's a photo of our tzoid's twins. This is a side by side comparison for you all:

    Ah hah! I've actually looked at that photo before. Should've noted the caption. Thanks Roy.

    12 oz. heavier, huh? Damn. According to Ty, the heavy is 6 oz. heavier, which just about had me sold on it. First, it looks bad (though no fluting is a bummer), and second, the heavies are only backed up 2 wks. whereas the lights are backed up 6 WKS.

    Choices choices.... :-\
