The Cobalt Kinetics A5-Ckh0 A5-Ck Buffer is a precision AR-15 buffer component engineered for shooters who demand reliability and consistency in their platform. Weighing 3.80 ounces, this H0-rated buffer is constructed from black anodized aluminum, offering corrosion resistance and a clean, durable finish. Whether you're running a dedicated range gun, a hunting rifle, or a defensive AR, the right buffer tuning is essential to cycling reliability and felt recoil management—and Cobalt Kinetics' A5 buffer line gives you the option to dial in your platform exactly as you need it.
This buffer is part of the A5 system, which uses a different spring and receiver geometry than the standard mil-spec AR-15 buffer tube. Before installing, confirm that your upper receiver and lower receiver assembly are compatible with A5-pattern components. The H0 weight specification matters: lighter buffers generally increase bolt carrier group speed and can run softer for precision work or suppressed fire, while heavier buffers slow the cycle rate and reduce felt impulse. A5 buffers are popular among precision shooters, match competitors, and hunters who want fine control over their rifle's behavior.
The black anodized aluminum construction resists corrosion in field conditions and pairs well with modern tactical or precision AR builds. Like all buffer components, it's a wear item and should be inspected periodically for damage or deformation. Pair it with the correct A5 receiver extension and spring for your intended use, and you'll have a tuned system that performs consistently round after round.

The A5-Ckh0 is an A5-pattern buffer. Confirm that your lower receiver and receiver extension (buffer tube) are designed for A5 components, not the standard mil-spec AR-15 geometry. If you're uncertain, check your rifle's manual or reach out to us—compatibility matters for both function and safety.
The H0 designation refers to the buffer's weight at 3.80 ounces. In an AR-15 system, buffer weight directly influences bolt carrier group speed, recoil impulse, and cycling rate. Lighter buffers (like this H0) generally allow faster cycling and can work well for precision shooting or suppressed setups where you want softer recoil. Heavier buffers slow the cycle for more control or reliable function with certain ammunition types.
We haven't been given the specific spring pairing in our product data, so we recommend contacting us or consulting Cobalt Kinetics' documentation to ensure you use the correct A5 spring for your buffer weight and intended use.
Yes. The A5-Ckh0 is used by hunters, precision competitors, and range shooters who value tuned cycling and recoil management. Its lightweight H0 rating makes it popular in builds where you want a soft feel and clean function, such as hunting rifles or match-grade ARs.
