The KAK Industry AR-15 A5-Length H2 Buffer is a heavy-duty recoil management component engineered for shooters running rifle-length AR platforms. This 5.5oz H2-weight buffer is machined from 7075 aluminum and finished with hard coat anodizing, delivering durability and consistent performance across thousands of rounds. If you're tuning a rifle-length AR-15 or AR-10 for reliability, reduced felt recoil, or optimized cycling with specific ammunition, an A5-length heavy buffer is a proven upgrade that works in tandem with your rifle-length buffer spring and A5-compatible tube.
KAK buffers are manufactured in the USA and built to last. The A5 system—longer and heavier than carbine-length alternatives—allows shooters to fine-tune bolt carrier velocity and dwell time. The H2 weight hits the sweet spot for many rifle-length builds, especially suppressed or heavily modified ARs where standard carbine buffers may cause unreliable feeding or excess wear. The anodized finish resists corrosion and wear, so your buffer maintains consistent dimensions and performance season after season.
Compatibility is non-negotiable: this buffer works only with A5-length buffer tubes and rifle-length AR-15 buffer springs. Pairing it with a carbine-length tube or spring will result in fit issues and reliability problems. Verify your current tube length and spring type before ordering. If you're assembling a rifle-length AR from scratch or swapping out a worn buffer, confirm your tube and spring specifications with your build documentation or manufacturer.

No. This is an A5-length buffer designed exclusively for rifle-length AR-15 platforms with A5-compatible buffer tubes and rifle-length springs. It will not fit or function in carbine-length systems. Verify your build uses an A5 tube before purchasing.
We don't have comparative weight data for other KAK buffers in the facts provided. The 5.5oz H2 weight is engineered to work with A5-length systems; if you need guidance on whether H2 is right for your specific build, contact us or consult your manufacturer's recommendations.
This buffer requires an A5-length buffer tube and a rifle-length AR-15 buffer spring. Using it with carbine-length tubes or springs will cause fit and reliability problems. Always confirm your current tube and spring specifications before installation.
The gold color is part of the hard coat anodizing process. This finish provides corrosion resistance and durability in addition to appearance, helping the buffer withstand field conditions and maintain consistent performance over time.
