Kynshot RB5006 Hydraulic Recoil Buffer - Stainless Steel AR-15

The Kynshot RB5006 hydraulic recoil buffer transforms AR-15 performance by replacing the standard carbine buffer with precision-engineered hydraulic dampening technology. This stainless steel buffer system reduces felt recoil by up to 70% while maintaining reliable cycling across all ammunition weights.

What Makes This Different

Unlike traditional weighted buffers that simply add mass, the RB5006 uses a sealed hydraulic system to control bolt carrier velocity throughout the entire recoil cycle. The stainless steel construction provides superior corrosion resistance compared to standard aluminum buffers. Independent testing shows consistent 2-3 MOA accuracy improvements due to reduced muzzle rise and faster target reacquisition.

Key Features

• Hydraulic dampening system reduces felt recoil up to 70%
• Precision-machined 316 stainless steel construction
• Compatible with standard carbine buffer tubes and springs
• Sealed system requires no maintenance or fluid changes
• 3.25-inch overall length fits standard AR-15/M4 platforms
• Temperature stable from -40°F to 160°F operating range
• Drop-in replacement for mil-spec H, H2, and H3 buffers

Range performance shows dramatic improvements in rapid-fire accuracy and shooter comfort during extended sessions. Competition shooters report faster split times between shots, while tactical applications benefit from reduced muzzle climb during controlled pairs. The hydraulic system maintains consistent performance across temperature extremes and high round counts without degradation.
