Kak Industry Llc. Ar-15 A5-Length H1 Buffer 4.64Oz Gold

The KAK Industry AR-15 A5-Length H1 Buffer is a heavy-duty carrier component built for shooters running modern direct impingement rifles with rifle-length gas systems. At 4.64 ounces, this H1-weight buffer is engineered to work with A5-length buffer tubes and rifle-length AR-15 buffer springs, giving you a proven platform for taming recoil and improving shot-to-shot consistency on the range or in the field. Whether you're tuning a precision build or upgrading a duty rifle, this American-made buffer delivers the reliability you expect without the premium price tag.

Built from 7075 aluminum and finished with hard-coat anodize, the KAK A5 H1 buffer is made to withstand thousands of rounds and years of hard use. The gold anodizing offers both durability and a clean, professional look. This is the kind of component that works quietly in the background—no tuning required, no compatibility headaches if you match it to the right tube and spring—just consistent performance.

The A5 system itself has become the go-to for shooters building rifles with rifle-length gas tubes, especially those looking to reduce carrier tilt and improve longevity. Pair this buffer with the correct A5 tube and spring, and you'll get a smoother, more controllable shooting experience compared to carbine-length setups.

Frequently Asked Questions

What buffer tube and spring do I need for this A5-length buffer?

This buffer is compatible only with A5-length buffer tubes and rifle-length AR-15 buffer springs. It will not work with carbine-length tubes or carbine springs. Double-check your receiver extension and spring before ordering.

Is this buffer suitable for a rifle-length gas system?

Yes. The A5-length H1 buffer is designed to work with rifle-length direct impingement gas systems. It helps reduce carrier tilt and manages recoil on builds using rifle tubes.

Is this buffer made in the USA?

Yes. KAK Industry manufactures this buffer 100% in the United States from 7075 aluminum.

What does the H1 weight mean?

H1 is a heavy buffer weight. It's meant to moderate the cycling speed of the bolt carrier group on rifle-length systems, resulting in reduced recoil and a softer shooting experience compared to lighter buffer options.
