Kak Industry Llc. Ar-15 A5-Length H4 Buffer 7.2Oz Black
The KAK Industry AR-15 A5-length H4 buffer is a heavy-duty tuning component built for shooters who run rifle-length buffer systems and want to dial in their AR's recoil impulse. At 7.2 ounces, this H4-weight buffer is engineered to slow bolt carrier velocity and reduce felt recoil—a smart choice if you're running a suppressor, a softer spring tune, or just prefer a smoother shooting experience. Made from 7075 aluminum and hard coat anodized, it's built to last without fussing.
KAK Industry backs this buffer with American manufacturing, so you know what you're getting: no mystery sourcing, no corner-cutting. It's the kind of part that bolts in and stays put through thousands of rounds. Whether you're a precision rifle shooter dialing in the perfect recoil profile or a hunter who values consistency in the field, this buffer gives you a straightforward, reliable way to tune your platform.
Before you order, confirm you're running an A5-length buffer tube and rifle-length buffer spring—this buffer is built specifically for that system. Swap it in, run your load, and feel the difference a quality buffer makes in your overall shooting experience.

Frequently Asked Questions
What buffer tube and spring do I need for this buffer?
This is an A5-length buffer, so it requires an A5-length buffer tube and a rifle-length AR-15 buffer spring. Do not use this buffer with a carbine-length tube or carbine spring—it won't function properly.
How does an H4 buffer affect my AR's shooting experience?
The 7.2 oz H4 weight slows down your bolt carrier's rearward travel, which reduces felt recoil and creates a smoother shooting impulse. It's especially useful if you're running a suppressor or prefer a softer, less snappy recoil profile than a standard buffer would give.
Is this buffer American made?
Yes. KAK Industry manufactures this buffer in the USA.
Will this buffer wear out?
The 7075 aluminum construction with hard coat anodizing is designed for a lifetime of reliable use, so you shouldn't need to replace it under normal conditions.
