LBE Unlimited ARBUFFH1 H1 Carbine Buffer AR-15 Silver Aluminum

The LBE Unlimited ARBUFFH1 H1 Recoil Buffer delivers precise cyclic rate control for carbine-length AR-15 platforms. This lightweight aluminum buffer reduces bolt velocity and smooths the action cycle compared to standard carbine buffers.

What Makes This Different

The H1 buffer weighs approximately 3.8 ounces, positioned between standard carbine (3.0 oz) and H2 (4.6 oz) buffers for optimal timing with most carbine gas systems. The silver anodized aluminum construction provides corrosion resistance while maintaining consistent weight distribution. This buffer addresses over-gassing issues common in shorter barrel configurations without requiring adjustable gas blocks.

Key Features

• H1 weight configuration (3.8 oz) optimized for carbine gas systems
• Silver anodized aluminum construction resists corrosion and wear
• Standard carbine buffer tube compatibility - direct replacement
• Tungsten weights provide precise mass distribution
• Reduces bolt carrier velocity for smoother cycling
• Compatible with all standard carbine buffer springs
• Fits mil-spec and commercial carbine extensions

The H1 buffer configuration proves effective with 14.5-16 inch barrels running carbine-length gas systems, particularly with lightweight bolt carriers or suppressed configurations. The controlled weight reduces felt recoil and muzzle rise while maintaining reliable extraction and ejection. Extended firing sessions benefit from the smoother bolt carrier deceleration.
