CMMG AR-15 Buffer Assembly H2 55CA92C | CMMG H2 Heavy Buffer for AR-15

Improve the reliability and shooting comfort of your AR-15 with the CMMG AR-15 Buffer Assembly H2 55CA92C. This heavy H2 buffer is designed to reduce felt recoil, smooth out the cycling action, and enhance overall performance in a wide range of AR-15 configurations. Manufactured by CMMG, a trusted name in the AR-15 industry, this buffer assembly provides the added mass needed to properly tune gas systems, especially in short-barreled rifles, suppressed firearms, and over-gassed setups. Whether you’re building a new rifle or upgrading an existing one, the CMMG H2 Buffer delivers consistent, reliable function while helping to reduce wear on critical components.

Why Choose the CMMG H2 Buffer Assembly?

The CMMG AR-15 H2 Buffer is an excellent upgrade for shooters looking to optimize their rifle’s performance. Standard carbine buffers are often too light for many modern AR-15 builds, leading to excessive recoil, bolt bounce, and accelerated wear on the buffer tube and receiver extension. The H2 buffer adds extra weight compared to a standard carbine buffer, helping to slow down the bolt carrier group and reduce the impact felt by the shooter. This results in a smoother shooting experience, improved accuracy during rapid fire, and better overall reliability. CMMG manufactures this buffer assembly to exacting standards using quality materials, ensuring it performs consistently across thousands of rounds. The H2 buffer is particularly beneficial for suppressed rifles, short-barreled rifles (SBRs), and pistols where gas pressure can be higher than ideal.

How the H2 Buffer Improves AR-15 Performance

The CMMG H2 Buffer Assembly works by increasing the mass of the reciprocating parts in the buffer system. When the rifle fires, the heavier buffer slows the rearward movement of the bolt carrier group. This delay allows chamber pressure to drop to safer levels before the bolt unlocks, reducing felt recoil and improving overall cycling smoothness. The result is less muzzle rise, faster follow-up shots, and reduced wear on the buffer tube, receiver extension, and lower receiver. Many shooters report a noticeable improvement in shootability when switching from a standard carbine buffer to an H2 buffer, especially in suppressed or short-barreled configurations.

Ideal for Suppressed and Short-Barreled Rifles

One of the most common uses for the CMMG H2 Buffer is in suppressed AR-15s. Suppressors increase back pressure, which can cause the rifle to cycle too quickly and violently. The added weight of the H2 buffer helps counteract this effect, resulting in more reliable function and reduced wear. It is also highly recommended for short-barreled rifles and AR pistols, where gas port sizes are often larger relative to barrel length. By slowing the action, the H2 buffer helps prevent premature unlocking and improves overall reliability in these specialized builds.

Direct Fit for Mil-Spec Buffer Tubes

The CMMG AR-15 Buffer Assembly H2 is designed as a direct replacement for standard carbine buffers. It fits all mil-spec carbine buffer tubes and works with most aftermarket stocks and receiver extensions. Installation is simple and requires no special tools, making it an easy upgrade for any AR-15 owner. The buffer comes pre-assembled and ready to install, saving time during builds or maintenance.

Built for Long-Term Reliability

CMMG manufactures this H2 buffer using quality materials designed to withstand the repeated impact and heat generated during shooting. The stainless steel weights resist corrosion and maintain consistent mass over time, while the polymer body helps reduce noise and vibration. This combination of materials ensures the buffer will continue to perform reliably through thousands of rounds of use.
