AR 15 H2 Carbine Buffer

The AR 15 H2 Carbine Buffer from Rare Breed Triggers is engineered to refine the cycling dynamics of your AR-15, particularly in carbine-length gas systems. Its weighted design ensures smoother operation, reduced recoil, and enhanced reliability, making it ideal for suppressed rifles, SBRs, and heavier calibers like .300 Blackout or 5.56 NATO.

What you get

• Heavyweight Design (H2): Combines steel and tungsten weights for a total mass of approximately 4.6 oz.
• Durable Construction: Crafted from aircraft-grade aluminum with a hard anodized finish.
• Improved Cycling: Enhances reliability in suppressed rifles, SBRs, and heavier calibers.
• Reduced Bolt Bounce: Ensures consistent operation during rapid fire or high-stress situations.
• Reduced Recoil: Adds weight to the buffer system, minimizing felt recoil and improving control.

Build and finish

The AR 15 H2 Carbine Buffer is constructed from aircraft-grade aluminum, a material chosen for its strength-to-weight ratio and durability. The hard anodized finish provides superior corrosion resistance, ensuring the buffer withstands harsh environments and prolonged use without degradation. This finish also reduces friction, contributing to smoother operation and longer service life.

Inside, the buffer combines steel and tungsten weights to achieve its H2 classification. Tungsten, denser than steel, allows for a compact design while maintaining the necessary mass to optimize cycling dynamics. This combination of materials ensures the buffer delivers consistent performance, whether in a suppressed rifle, an SBR, or a standard AR-15 configuration.

Compatible platforms

• AR-15 rifles with carbine-length gas systems.
• Suppressed rifles and short-barreled rifles (SBRs).
• Firearms chambered in .300 Blackout or 5.56 NATO.
• Any AR platform requiring a heavier buffer for improved cycling.

Installation notes

Installing the AR 15 H2 Carbine Buffer is straightforward: remove the old buffer from the buffer tube, insert the H2 buffer, and reassemble. Ensure compatibility with your rifle’s gas system and caliber before installation. For suppressed rifles or SBRs, this buffer often provides noticeable improvements in cycling and recoil management.

Like the modularity of Polymer80 frame builds, the AR 15 H2 Carbine Buffer is another example of how precision-engineered components can enhance firearm performance. Whether you’re fine-tuning an AR-15 or assembling a custom build, this buffer offers a reliable upgrade for smoother operation and better control.
