Kak Industry Llc. Ar-15 A5-Length H3 Buffer 6.34Oz Gold

The KAK Industry AR-15 A5-Length H3 Buffer is a heavy-duty receiver extension component engineered for rifle-length AR platforms. Built from 7075 aluminum and hard coat anodized for durability, this 6.34 oz buffer delivers the mass and resilience you need for reliable cycling across a range of upper configurations. It's designed to work exclusively with A5-length buffer tubes and rifle-length AR-15 buffer springs—a setup that gives you more bearing surface and smoother operation than standard carbine-length systems.

A5 buffers are the choice of builders who want a slightly longer dwell time and softer recoil impulse without chasing additional tuning. Whether you're running a mid-length or rifle-length gas system, this H3 mass lets your bolt carrier group function predictably. The gold anodize isn't just cosmetic—it's a marker of KAK's commitment to corrosion resistance and longevity. Made in the USA and built to last, this buffer won't let you down on the range or in the field.

If you're upgrading a rifle-length AR or fine-tuning your semi-custom build, confirm that your lower receiver and buffer tube are A5-spec before purchasing. This is not compatible with carbine-length tubes or springs.

Specifications

Frequently Asked Questions

Is this buffer compatible with my AR-15 carbine?

No. This is an A5-length buffer designed exclusively for rifle-length AR-15 systems with A5-length buffer tubes and rifle-length buffer springs. It is not compatible with standard carbine-length setups.

What makes an A5 buffer different from a standard carbine buffer?

A5-length buffers work with longer buffer tubes and springs, offering more bearing surface and a longer dwell time. This typically results in softer recoil impulse and smoother operation, especially useful in mid-length and rifle-length gas systems.

Will this buffer work with my rifle-length gas system?

Yes, if your lower receiver accepts A5-length buffer tubes. Always verify your buffer tube spec before purchasing—compatibility depends on matching the tube length and spring type to the buffer.

What's the difference between H3 and other buffer weights?

The H3 designation indicates this is a heavy buffer at 6.34 oz. Heavier buffers slow down the bolt carrier group's rearward travel, reducing felt recoil and potentially improving reliability in suppressed or short-barreled configurations. Your choice depends on your gas system tuning and desired cycling speed.
