  1. Rated 4 out of 5


    I purchased this barrel to complete a pistol build using an Anderson sport upper and AM-15 lower. Fit and finish is fantastic! I only give this 4 stars because I have not shot it yet. All Anderson products were used in this build and I could not be more pleased.

  2. Rated 5 out of 5


    I have found this barrel exceptionally accurate with all types of 556 ammo commonly found. Highly recommended if you want a watering can of biblical proportion, cheap to shoot, accurate, and of great quality.

  3. Rated 5 out of 5


    Good price, fit and finish were much better than a more expensive one I bought from “Garry”. Will be buying another one for another build.

    Is it chromed lines

    • Tom Steffner

      No Sir

  5. Rated 5 out of 5


    This is really a great barrel I’m glad I went with this one on my Anderson Ar, close or far I still have great accuracy with 1:7 twist and the luxury of close quarters and light weight mobility. Quality fast shipping also.

    Do your barrels come dimpled for block set screws or pin ready for A2 style?

    • Michael Johnson

      No the barrels do not come with the dimples for gas blocks

  7. Rated 5 out of 5


    Great barrel at a great price. I’ve used these on different occasions and they work great from SBR to AR pistol builds. Accurate and well made.

    Does this barrel have the two holes drilled for the A2 front Sight Post Taper Pins or will I have to have them drilled into it after I purchase the barrel

    • Tom Steffner

      You will need to drill after purchase
