    Lightweight while still being very precise

    You can definitely feel the lower weight. It makes the rifle more nimble and maneuverable. Also, the mid-length gas system with a standard carbine buffer and spring makes for a relatively soft-shooting rifle. Haven't grouped it with bipod/sandbags yet, but it seems to be well under 2 MOA.

    I'm happy.

    KAK shipped this item super fast which I appreciate. The quality was better than any "value line" barrel I have used and when I get the bug again I will be back. Great way to build out a light weight project.

    Great looking barrel

    First let me say that the shipping and customer service from KAK are amazing. The barrel looks great and fits the upper like it should, I can't wait to get my flash hider welded so I can get this thing to the range.

    Very Impressed

    Posted by Daygooz3v on May 17, 2016

    I am very impressed with the quality of this barrel. Fit and finish is excellent and am very impressed with the accuracy as well. I've only put about 300rds through the gun so far but so far so good. I'm planning on getting the 18" value line barrel for my next build. I plan on only using KAK barrels from now on

    Great barrel for the money

    Great looking barrel with an all around good finish. Fit real snug into my upper receiver. Have not shot it yet but so far for the price it can't be beat.
