The KynSHOT RB5015HD is a heavy-damped hydraulic recoil buffer designed for AR-9 / PCC platforms. Engineered as a drop-in replacement, it pairs with standard buffer springs and is optimized for 9mm loads and PCC barrel lengths of 8″ and up. Constructed from stainless steel and developed in cooperation with Blitzkrieg Components, the RB5015HD is intended to reduce felt recoil and improve follow-up accuracy in supported configurations.
Key Specifications
- The model is RB5015HD.
- Designed to fit AR-9 / PCC platforms.
- Compatible with 9mm loads.
- Optimized for PCC builds with barrel lengths of 8 inches and up.
- Constructed from stainless steel.

The RB5015HD provides a practical, reliability-focused upgrade for shooters building or maintaining AR-9/PCC rifles. Its stainless construction and hydraulic damping make it a straightforward solution for reducing recoil impulse and improving follow-up consistency in supported setups. For users running suppressed PCCs or 8″+ barrels, this buffer is sized and tuned to stop reliably near the bolt catch while smoothing the cycling impulse.
