    Great, budget friendly pistol barrel. Been hard to find in stock for the past couple weeks but once in stock I jumped on it. No problems for me.

    Another Quality Barrel !!!

    Posted by Larry D. on July 24, 2018

    I ordered this barrel to replace the barrel on an upper I purchased "on sale".... taking the risk it would shoot well enough for 50 yards. But it didn't....so I knew were to get a better barrel.....KAK !!! I have 2 of the stainless 8" barrels, and decided this Value Line would do the job I was looking for. As usual....KAK barrels always work for me !!! This barrel shoots about 1.5" groups with a 2 moa RDS..,.. perfect !! Buy this barrel for your builds !!!

    Barrel is really nice. Although it gets really hot after continuous shooting of a 30 round mag.

    I ended up buying this barrel as a replacement for a poor shooting (other brand) barrel on my AR pistol build.I am very impressed with the accuracy, ended up taking it out to 200 yards and could easily hit a 6" steel target I had set up with ease.Fit/Finish/chamber/threading all superb.I am a machinist by trade and tend to get picky with finish and quality.Great bang for the buck..this barrel outshoots the first barrel I purchased and it was almost 3x the cost of what I paid for this KAK!

    Wow impressive

    I wouldn't ever thought of buying a barrel this cheap but I must say that this is one nice barrel the finish is absolutely amazing. Heavy feel like quality metal should feel. Accuracy is dead on . I recommend this product to anyone on any budget. I have bought 200 dollar plus barrels and I wish I would have looked at kak first. Shipping was so quick that I couldn't believe it , ordered on 9/29/2016 at my door 10/1/2016. This is how business should be done!!!!
