    Nice barrel for the price but...

    Posted by Casey on August 15, 2020

    I really wanted to give this barrel 5 stars on the quality but it has 1 small problem, the head space is .001" long [1.635"] which means it will close on a NOGO gauge. This has been a problem with the last 3 barrels I have ordered from other manufactures, while this is not a death nail to the barrel as long as it does not close on a Field gauge it is still safe to shoot. If I had a bolt that was NIB coated it probably would not close on a NOGO gauge but of the 3 bolts I tried it is long. I am not bad mouthing KAK as every other product I have ever ordered from has been fine and it will not stop me from ordering from on the future. This is the problem with building AR 10/LR 308's rifles, there are no real standards like parts for a AR15. I am going to use this barrel and it will probably be reliable and accurate.

    This isn't the first product that I've bought from KAK. I'LL NEVER BUY A BARREL FROM ANY OTHER MANUFACTURER. These products are top notch and the prices are good.

    good barrel for the money

    Posted by troy on January 14, 2018

    Pros- fitment and quality were excellent. shooting three different loads, the 175gmm was by far the most accurate factory load at a repeated 0.8 moa. the second most accurate was 168gmm at still under an inch. Loads developed for another DPMS style match rifle with a criterion barrel would not shoot in this barrel at all. Leads me to the only downside I found with this barrel. Cons- my particular barrel had a very short free bore restricting me to loading a bit shorter than I usually do for this type of rifle. Not a big deal. I would have preferred to see a recessed crown but understand at the price point KAK sells this gun at, every additional machine operation directly adds to the final cost. I would speculate recessing the crown would add 10 or 15 bucks and dimpling an extra 8 to 10 dollars. If these operations are problematic for you, buy one of there barrels that incorporate them already. Bottom line- A very reasonably priced no frills barrel that shoots at or near minute of angle. I'm pretty impressed.

    I am impressed with the barrel. The fit to my upper was tight. The finish was uniform. It was even better considering the price. Love the barrel and will order on again on my next build.
