    This is the third barrel I've purchased from KAK, They sell a top shelf product, I've never had an issue with any of their products, I just wished they made a 10.5" .458 Socom barrel

    Great barrel

    Posted by Philip on July 5, 2018

    Picked this value barrel and thought I was gambling on a cheap barrel to change the length of my AR. Quality was better than I expected. Threaded on with ease. No issues with install. Sub 1 inch at 100 yards after three different bullet types and they were all within an inch just one of them was less than half an inch. Will be ordering from KAK again. No issues. No complaints. Shipped much faster than I expected. Overall top quality. My only complaint or issue is that when KAK labels it as a value barrel, it misrepresents that quality that they deliver at the price point. They should call it the awesome barrel at an discount price barrel. Thank you KAK industries. I was beyond pleased with the entire process start to finish.

    Better than expected

    Having the barrel be called value line made me hesitant to buy one but for the price I took a chance and I'm really happy I did. I installed the barrel on a billet boot leg upper and it fit perfectly. Put over 300 rounds thru it first day at the range and no issues and great grouping at 50 and 100 yards.

    This barrel is titties!

    Profile is sweet, no shitty cut in the barrel for a grenade launcher you'll never get! Profile is in between a Gov't and SOCOM. It goes from .750 to .740 all the way to the muzzle device. I've got a dude who makes 3 prong flash hiders at a .740 profile for a permanent attachment to a 14.5 barrel for a 16" total length and the gas block slides over it! The gas port on these is a little bigger so it cycles all ammo no problem and it hits what you're aiming at! Just buy it! On another note, Kurt the owner is responsive and helpful. I've purchased MANY of their products and the KAK shockwave blade with buffer tube is out-freakin-standing! If you have any questions, hit me up at blackriflelife@gmail.com
