KYNSHOT RB5000L Hydraulic Buffer 300 Blackout AR-15 Recoil System

The KYNSHOT RB5000L hydraulic buffer transforms 300 Blackout AR-15 performance by eliminating bolt bounce and reducing felt recoil through precision-engineered hydraulic dampening technology. This buffer system delivers consistent cycling across subsonic and supersonic loads while extending component life.

What Makes This Different

Unlike standard carbine buffers that rely solely on weight and springs, the RB5000L incorporates a sealed hydraulic system that actively controls bolt carrier velocity throughout the entire cycle. The internal hydraulic mechanism provides progressive resistance that adapts to different ammunition weights and velocities. This technology reduces bolt bounce by up to 80% compared to conventional buffer systems, resulting in faster follow-up shots and improved accuracy.

Key Features

• Sealed hydraulic dampening system eliminates bolt bounce and carrier slam
• Optimized 5.0-ounce weight specifically calibrated for 300 Blackout cycling
• Compatible with standard carbine buffer tubes and extension springs
• Reduces felt recoil and muzzle rise for faster target reacquisition
• Internal nitrogen charge maintains consistent performance across temperature ranges
• Precision-machined aluminum construction with anodized finish
• Drop-in installation requires no gunsmithing or modifications

The RB5000L excels in tactical applications where rapid follow-up shots matter most. Competition shooters report improved split times and reduced group sizes, while law enforcement agencies value the enhanced control during rapid fire sequences. The hydraulic system maintains consistent performance with both 110-grain supersonic and 220-grain subsonic loads, making it ideal for suppressed applications where cycling reliability becomes critical.
