The Cobalt Kinetics A5-CKH1 buffer is a purpose-built AR-15 recoil management component designed for shooters running direct-impingement systems who want a heavier weight option. At 4.56 ounces, the H1 buffer sits at the heavier end of the buffer spectrum and is constructed from black anodized aluminum—a durable finish that resists corrosion and blends with modern AR builds. Whether you're tuning a rifle for suppressed fire, managing a hard-kicking cartridge, or optimizing your bolt carrier group dynamics, a dedicated buffer weight gives you real control over cycling speed and felt recoil.
Buffers are a foundational part of your AR's tuning system. The H1 weight works in concert with your bolt carrier, hammer spring, and gas port geometry to dial in reliability and reduce wear on internal components. If you've already dialed in your gas block or are running a suppressor that changes your system's gas profile, swapping to the right buffer weight is often the smartest next step—cheaper and faster than chasing a new upper or adjusting your gas system itself.
Cobalt Kinetics brings precision manufacturing to buffer production. The H1 fits standard A5 extension tubes (not the older A2 tube), so verify your upper receiver compatibility before ordering. Black anodized aluminum stands up to hard use and looks good doing it.
| Brand | Cobalt Kinetics |
| Model | A5-CKH1 |
| Buffer Weight | H1 (4.56 oz) |
| Material | Aluminum, black anodized |
| Tube Compatibility | A5 extension tube |
The Cobalt Kinetics A5-CKH1 is designed for AR-15s running an A5 extension tube. If your upper receiver uses a standard A2 buffer tube, this buffer will not fit. Verify your current setup before purchasing.
An H1 buffer slows your bolt carrier's cycling speed and reduces felt recoil. Consider it if you're running a suppressor, shooting heavy magnum cartridges, experiencing reliability issues due to overgassing, or want to minimize hammer follow and bolt bounce.
The Cobalt Kinetics H1 buffer weighs 4.56 ounces, making it one of the heavier standard buffer options available.
