Recommended Uses and Applications

Precision AR Builds for Competition/Duty Use

The Geissele Super 42 H2 Buffer is a highly recommended component for precision AR builds intended for competition or duty use. Its innovative design and construction make it ideal for enhancing the overall performance and reliability of your AR-15.

Whether you’re participating in shooting competitions or serving in a law enforcement role, this buffer will help you achieve greater accuracy and consistency in your shots.

The Super 42 H2 Buffer is engineered to absorb recoil and reduce bolt bounce, resulting in smoother operation and faster follow-up shots. This is particularly beneficial for shooters who need to quickly engage multiple targets or maintain tight shot groupings during competitive shooting scenarios.

When every shot counts, the Geissele Super 42 H2 Buffer is a must-have component.

Rifles with Adjustable Gas Blocks

If you own an AR-15 rifle equipped with an adjustable gas block, the Geissele Super 42 H2 Buffer is an excellent choice to optimize the performance of your firearm. The buffer’s H2 weight configuration is specifically designed to work with rifles that have adjustable gas systems.

By adjusting the gas block, you can control the amount of gas that is directed to the buffer, which affects the cycling speed and recoil impulse of the rifle. The Super 42 H2 Buffer complements this feature by providing a consistent and reliable buffer response, regardless of your gas system settings.

Whether you prefer a softer shooting experience or a more aggressive cycling action, the Geissele Super 42 H2 Buffer allows you to fine-tune your rifle’s performance to your liking, maximizing both comfort and control.

Builds Using Sound Suppressors

For those who enjoy shooting with sound suppressors, the Geissele Super 42 H2 Buffer is an ideal choice. When firing a suppressed AR-15, the increased backpressure can cause the rifle to cycle more violently, leading to increased felt recoil and potential reliability issues.

The Super 42 H2 Buffer, with its enhanced weight and increased mass, helps to mitigate these issues by providing additional energy absorption and reducing bolt bounce. This results in a smoother and more reliable cycling action, even when shooting with a suppressor.

By using the Geissele Super 42 H2 Buffer in your AR-15 build, you can experience the benefits of shooting suppressed without sacrificing performance or reliability. Whether you’re engaging in tactical training or enjoying some quiet plinking at the range, this buffer will enhance your shooting experience.

Potential Alternatives from Other Brands

JP Enterprises Silent Captured Spring

If you’re in the market for an alternative to the Geissele Super 42 H2 Buffer, the JP Enterprises Silent Captured Spring is worth considering. This innovative buffer system replaces the traditional buffer and spring with a self-contained unit that eliminates the “twang” sound often associated with the cycling of an AR-15.

The JP Enterprises Silent Captured Spring offers a smoother and quieter operation, making it a popular choice among competitive shooters and those who prioritize reduced noise.

Spike’s Tactical Viper H2

Another alternative to the Geissele Super 42 H2 Buffer is the Spike’s Tactical Viper H2 buffer. This buffer is designed to provide enhanced recoil control and improved reliability.
