    Excellent barrel for the money. This barrel cycles all ammunition subsonic and supersonic loads unsuppressed. I highly recommend this barrel and Anderson Rifles products. Their customer support is outstanding.

    I was building a 300BO Pistol and attempting to use an 11.5″ barrel with a carbine length gas system. With Subsonic 220gr @ 1000fps this combination was severely under-gassed. I purchased the 10.5″ Pistol Gas System Barrel and it has been superb!!! Anderson Manufacturing was fast, informative and the barrel is great. Thank you.

    Awsome product very fast shipping. Just what I needed. Runs flawless no matter what I feed it super and sub sonic. Even inconsitant reloads. Would tell anyone to buy this for a 300 build. Thank you.

    @Jeff and Michael Johnson Mine was dimpled for gas block for one set screw, not two. Regardless nice touch and lined up gas block perfect.
