KYNSHOT RB5000 Hydraulic Recoil Buffer AR-15 Carbine Stock System

The KYNSHOT RB5000 hydraulic recoil buffer transforms AR-15 carbine performance by replacing traditional spring-driven systems with precision hydraulic dampening technology. This advanced buffer system reduces felt recoil by up to 70% while eliminating bolt bounce and cyclic rate variations that plague standard carbine configurations.

What Makes This Different

Unlike conventional buffer springs that compress and expand inconsistently under rapid fire, the RB5000 utilizes a sealed hydraulic cylinder with metered fluid flow to control bolt carrier group movement. The system maintains consistent back pressure across temperature ranges from -40°F to 160°F, delivering predictable cycling regardless of ammunition type or firing rate. This technology originated from military applications where reliability under extreme conditions determines mission success.

Key Features

• Hydraulic dampening system reduces felt recoil up to 70% compared to standard buffer springs
• Eliminates bolt bounce and carrier group slam for improved accuracy and component longevity
• Temperature-stable performance from -40°F to 160°F with sealed fluid chamber
• Drop-in replacement for mil-spec carbine buffer tubes requiring no modifications
• Compatible with 5.56 NATO, .223 Remington, and .300 Blackout chamberings
• Precision-machined aluminum construction with hard-coat anodized finish
• Self-contained system requires no external adjustments or maintenance

The RB5000 excels in competitive shooting environments where split times and follow-up shot accuracy determine placement. Law enforcement and military users benefit from reduced muzzle rise during rapid engagement sequences, while hunters appreciate the system's ability to maintain zero integrity after extended transport. The hydraulic design functions reliably with suppressed configurations, managing increased back pressure without cycling issues common to over-gassed systems.
