The Cobalt Kinetics A5-CKH4 buffer is a purpose-built H4 weight component for AR platform rifles using the A5 buffer tube system. At 6.83 ounces, this buffer strikes a balance suited to a range of shooting applications—from general plinking and competition to field hunting. Cobalt Kinetics designs their buffers to work within the A5 ecosystem, which has become a go-to choice for shooters looking to fine-tune recoil management and cycling characteristics on their uppers.
Buffer weight is one of the simplest and most effective tuning tools in an AR-15 or AR-10 build. The H4 sits in the heavier category, which generally slows bolt carrier velocity and can reduce felt recoil and muzzle rise—handy if you're running a rifle with a stiff spring rate, a lighter upper, or a gas system that's tuned on the aggressive side. It can also help stabilize function with suppressed loads or when running ammunition that's on the softer end of the spectrum.
The black anodized aluminum construction is durable and corrosion-resistant, a standard that keeps maintenance straightforward. Because buffer selection is highly dependent on your rifle's gas port diameter, spring rate, ammunition, and whether you're running a suppressor, we recommend verifying compatibility with your specific A5-equipped rifle before installation.
| Brand | Cobalt Kinetics |
| Model | A5-CKH4 |
| Weight | 6.83 oz |
| Buffer Weight Class | H4 |
| System Compatibility | A5 Buffer Tube |
| Material | Black Anodized Aluminum |
The A5-CKH4 is designed for rifles with A5 buffer tube systems. Before purchasing, confirm your rifle uses an A5-compatible tube rather than a standard mil-spec tube; they are not interchangeable.
The H4 weight slows bolt carrier velocity and typically reduces felt recoil and muzzle rise compared to lighter buffers. This can improve control and help with function when running suppressed ammunition or stiffer spring rates.
Buffer weight directly influences cycling. Function depends on your gas port diameter, gas tube system, spring rate, suppressor use, and ammunition power level. If your rifle is running well with a different buffer weight, confirm compatibility before switching to the H4.
