LBE Unlimited H2 Recoil Buffer Carbine AR-15 Silver Aluminum

The LBE Unlimited ARBUFFH2 H2 Recoil Buffer delivers enhanced cycling control for carbine-length AR-15 platforms through precision-weighted tungsten construction. This buffer addresses common cycling issues in shorter-barreled rifles while reducing felt recoil and bolt bounce.

What Makes This Different

The H2 buffer weighs approximately 4.6-4.7 ounces compared to standard carbine buffers at 3.0-3.8 ounces, providing optimal bolt carrier group timing for 14.5-16 inch barrels. The additional weight comes from tungsten inserts rather than steel, offering superior density in a compact design. This configuration reduces over-gassing symptoms common in carbine-length gas systems while maintaining reliable extraction and ejection.

Key Features

• H2 weight configuration optimized for carbine-length gas systems
• Precision-machined 6061-T6 aluminum body with anodized silver finish
• Tungsten weight inserts for maximum density and durability
• Standard carbine buffer tube compatibility (Mil-Spec and commercial)
• Reduces bolt bounce and improves brass ejection patterns
• Compatible with standard carbine buffer springs
• Manufactured to military specifications for consistent performance

Field testing demonstrates improved cycling reliability in suppressed configurations and with various ammunition weights. The H2 buffer particularly benefits rifles experiencing extraction issues, erratic ejection patterns, or excessive bolt velocity. Competition shooters report more consistent brass patterns and reduced muzzle climb during rapid fire sequences.
