I received the [link removed] barrel instead of the [link removed] as listed here. After contacting customer service and providing sufficient evidence that I was sent the wrong product—one I never intended to purchase—the subsequent response was disappointing. The attempt made by at3 to contact KAK proved futile due to KAKs alleged inability to distinguish between their own [link removed] and [link removed] barrels. Even though I provided video evidence, which shouldn’t have been necessary considering the clear differences in the indentations/rings and the distance between the gas port and muzzle (details visible on any picture or listing for these barrels including this one ), AT3 told me the only way to resolve the issue was to return it for a refund.

While I appreciate the fast response from customer service, it’s concerning and off-putting that the [link removed] barrel is still listed as in stock on the site, despite the product being proven illegitimate.

  1. Hello, I purchased a KAK 12.5 mid length barrel and I'm wanting to know if you think it will run fine unsuppressed? Also if I would need a adjustable gas block? Any information would be greatly appreciated.

    AT3 Support Team — Yes, the KAK Industry 12.5" Mid-Length 5.56 NATO barrel runs reliably unsuppressed out of the box, as it's designed to be overgassed for consistent cycling with various ammo—even after 20k+ harsh rounds in tests. An adjustable gas block isn't required but is highly recommended if you plan to run it suppressed too, allowing you to tune gas flow for optimal performance and reduced recoil in both setups. Many users pair it with an H2 buffer and standard BCG for great results unsuppressed.
