Is the Geissele H2 Buffer Right for You?

Determining whether the Geissele H2 buffer is the right choice for your AR-15 depends on several factors, including your rifle’s configuration, the type of ammunition you typically use, and your shooting style. Consider the following points:

AR-15 Configuration

The configuration of your AR-15 can have a significant impact on which buffer weight is most appropriate. Rifles with shorter barrels or gas systems may benefit from a heavier buffer like the Geissele H2 buffer, as they tend to cycle more aggressively. Conversely, rifles with longer barrels or gas systems may perform better with a lighter buffer. It’s essential to consider the overall length and gas system of your rifle when selecting a buffer. The Geissele H2 buffer often works well with 14.5″ and 16″ barrel configurations.

Ammunition Type

The type of ammunition you use can also influence your choice of buffer weight. Some ammunition types, such as those with higher pressures or heavier bullet weights, may generate more recoil energy. In these cases, a heavier buffer like the Geissele H2 buffer can help to manage the recoil and maintain reliable cycling. If you primarily use low-powered ammunition, a lighter buffer may be more appropriate. Experimentation and testing are often necessary to find the optimal buffer weight for your preferred ammunition.

Shooting Style

Your shooting style can also play a role in determining the right buffer weight. If you primarily engage in rapid fire or competitive shooting, a heavier buffer like the Geissele H2 buffer can help to improve your control and accuracy. The reduced recoil and muzzle rise can allow you to stay on target more easily and make faster follow-up shots. If you primarily shoot at a slower pace, a lighter buffer may be sufficient. Consider how you intend to use your AR-15 and choose a buffer weight that complements your shooting style.

Installing the Geissele H2 Buffer

Installing the Geissele H2 buffer is a relatively simple process that can be completed with basic tools. However, it’s important to follow the instructions carefully to ensure proper installation and function. Here’s a step-by-step guide:
