    Great barrel and high quality

    Posted by Albert on May 15, 2020

    This is my 3rd barrel from KAK so I already knew that it would be a quality product and I was not disappointed, its a great shooter, as are the other 2. The finish on this barrel is as good as any of the higher priced barrels. My personal opinion you cannot go wrong with any of KAK's barrels.

    Excellent barrel

    Posted by Anthony on January 3, 2020

    I purchased this 8" barrel for my Palmetto State Armory AR9 to replace the 10.5" barrel. 1,500 rounds later and I have no complaints. One thing worth mentioning is, in the photos on the KAK website, the barrel looks like a gold/bronze color which I was pretty excited about. When I received the barrel, I discovered it's in fact just a standard black color. Oh well, still a great price and a great barrel.

    Very Nice 9mm Option

    Posted by Kevin on November 25, 2019

    This barrel was used with the KAK BCG and I am achieving very good accuracy and consistent shots. Have not had a single issue with it yet. And would look to buy more of these value line barrels in the future.

    Great barrel but needs some modifications for certain glock mag adapters

    Posted by Ian on November 6, 2019

    This barrel is made well and very accurate. I was getting 3moa at 100m. I'm using a glock mag adapter made by stern defence, kak bolt and kak 5.5oz buffer. Fed 115 grain fine but 124 grain was getting stuck half way in the chamber at an angle. Also noticed brass bits all over the bolt so upon further research I found that this kak barrel seems to be designed best for feeding from colt/uzi magazines. Glock mags have a odd feed angle and are more finicky with feeding. I ended up grinding a large feed ramp into the bottom chamber area with a dremel. Works great now with the glock mag adapter and there are no brass shavings on the bolt anymore. All in all a great barrel and a great price just be prepared to possibly do some feeding modifications if you are using glock magazines.

    Excellent Value

    Fit and finish are as good as some of the more expensive brands I have used. Accurate and works great on my pistol build. Will do business with KAK again.

    Barrel was tight in some uppers

    Posted by Eric on November 13, 2016

    This barrel was tight two aero blem uppers with forward assist and dust covers. However, barrel fit as expected with two Anderson uppers without forward assist or dust cover.
