    Bought this barrel for my build about 6 months ago and it has performed great since, I doubt I could have made a better choice of barrel.

    I recently bought an Anderson am15 from my local pawn shop. They said the rifle was new and unfired but had a previous owner. I looked at the barrel and on the top it is stamped R 5.56 NATO 1×7. Is this y’all’s barrel? If not do you have any idea who’s it could be? It is also an m4 profile. Thanks.

      It’s ours

    Building an ar15 black rifle for LE use…wondering what you recommend. Currently have mega arms lower, just looking for barrel. Hearing 1/7 chrome lining is best. Thanks!!

    • Tom Steffner

      Chrome lining is to combat corrosion, if your looking for accuracy choose a barrel that’s not chrome lined.

    This barrel just came in the mail and it is perfect. it shoots all types of rounds from 55gr. to 79 gr.

  15. Rated 5 out of 5


    Purchased this barrel for an AR build recently and have put about 300 rounds through it so far flawlessly!! You can get about 3-4 inch groupings at 100 yards with iron sights! Cannot be more impressed with this product. Check out my OutdoorEnthusiast88 YouTube channel for some in depth reviews on this specific barrel. Great barrel for a high quality budget AR build.

    Can I use a mid length gas tube with this barrel?

    • Michael Johnson

      No this barrel has a carbine gas set up.

  19. Rated 5 out of 5


    Not a review, but how many rounds would you say this barrel will last? 10,000-15,000 rounds? I’ll be a weekend and sometimes a once a month shooter

    • Michael Johnson

      most barrels last about 8k rounds before you see some issues with the rifling.
      If you buy an RF85 barrel you can get 15k rounds.
