    Another great product from Anderson. Item arrived in perfect condition. Accepted all the Anderson parts with no issues. Mated well the Anderson upper. Barrel is of high quality without the gut punching prices. You will not be disappointed. Thanks again Anderson…

    Excellent barrel. Just as described. Doesn’t have barrel caliber or twist engraved on it but ill get over that. lol. Cant wait to finish my pistol build. The price was amazingly low and affordable. Sweet product. Will buy from Anderson again and recommend to new customers.

    Purchased one of these barrels for a pistol build on one of Anderson’s lowers. Build turned out awesome. Most of the components where Anderson parts; barrel, lower, upper and bcg, matched with a Sig Arm Brace this pistol is a sweet little plinker at the range. Can’t wait to order parts for another shortie upper in 300blk. Thanks for great products at reasonable prices.

    Barrel just came in and looks great, installing on pistol I’m building. Just trying to figure out what size threads it is for the flash hinder. Anyone know?

    Not a review, question. Does this have gas block dimples already there?

    • Michael Johnson

      No this barrel does not have the dimples for the set screws.

    Can you shoot steel cased ammo reliably through this barrel

    • Michael Johnson

      Yes you can shoot it.
      may cause some issues since the heat will cause it to expand.
      Prefer brass

    Do I need to get dimples drilled for the gas block? Or can I just tighten the screws?

    • Michael Johnson

      you can just tighten the screws.

    I’m a disabled combat vet trying to build an AR pistol on a budget. I recently bought your $200 RF85 complete pistol lower with Magpul grip, a great value.

    Is there any chance you’ll be offering this barrel and price again soon?
