LBE Unlimited ARBUFF9MM 9mm AR-15 Carbine Recoil Buffer Black

The LBE Unlimited ARBUFF9MM Carbine Recoil Buffer transforms 9mm AR-15 builds by managing bolt velocity and reducing felt recoil through precision-engineered hydraulic dampening. This specialized buffer addresses the unique cycling characteristics of pistol caliber carbines, which operate differently than standard 5.56 systems. The result is smoother operation, reduced wear on components, and improved shooter comfort during extended range sessions.

What Makes This Different

Unlike standard carbine buffers designed for rifle cartridges, the ARBUFF9MM features internal dampening specifically calibrated for 9mm blowback operation. The hydraulic system controls bolt speed throughout the entire cycle, preventing the harsh slam associated with straight blowback actions. This controlled deceleration reduces stress on the bolt catch, lower receiver, and buffer tube while maintaining reliable extraction and ejection.

Key Features

• Hydraulic dampening system optimized for 9mm blowback operation
• Reduces felt recoil and muzzle rise for faster follow-up shots
• Standard carbine buffer tube compatibility - no modifications required
• Precision-machined aluminum construction with black anodized finish
• Internal tungsten weights provide proper mass for reliable cycling
• Sealed hydraulic chamber prevents contamination and leakage
• Compatible with all AR-15 pattern 9mm builds and conversions

The ARBUFF9MM delivers consistent performance across various 9mm loads, from 115-grain practice rounds to 147-grain subsonic ammunition. Competition shooters benefit from the reduced recoil impulse during rapid-fire stages, while law enforcement and security professionals appreciate the enhanced controllability during training exercises. The buffer maintains reliable function in adverse conditions, with the sealed hydraulic system protecting against dust, moisture, and temperature fluctuations.
