NPAS System For Double Eagle GBB – Adjustable Power Control (2-Pack, £10)

Take full control of your Double Eagle GBB rifle’s performance with our precision-printed NPAS system. Designed and built specifically for Double Eagle GBB platforms, this system lets you fine-tune your rifle’s power output for maximum consistency and legal compliance.

If your rifle is shooting over the field limit, simply turn the grub screw clockwise to reduce FPS. Using heavier BBs? The NPAS helps maintain a safe and stable joule output — keeping your setup efficient and field-ready.

Each valve is 3D-printed with 245 layers of high-strength PA12 carbon-fibre–infused nylon, offering outstanding durability and temperature resistance. We’ve tested these units over thousands of rounds with zero structural failures.

As NPAS valves are considered consumable parts, natural wear will occur over time — that’s why we include two valves per pack, so you always have a spare ready to go.
