Transfer Port BinTac PA 30 – airgun flow adapter

The Transfer Port BinTac PA 30 is a precision-machined adapter for .22 calibre air rifles. It regulates airflow between the valve and the projectile through a calibrated 1mm port, delivering a consistent energy output of 14.2 Joule. The component is finished in silver chrome for corrosion resistance.

Construction and materials

The adapter is manufactured to tight tolerances to ensure a leak-free seal within the action. Its silver chrome finish protects against oxidation and wear caused by repeated pressurisation cycles. The central 1mm bore is precisely drilled to maintain stable flow characteristics shot after shot, supporting predictable velocity behaviour across strings.

Application and use

This transfer port is intended for users who tune their air rifles for specific projectile weights and energy targets. It is optimised for 50.15 grain pellets or slugs in .22 calibre, making it suitable for precision shooting, hunting, and field target disciplines where a controlled 14.2 Joule output is required. Heavier projectiles benefit most from the restricted port geometry.

Integration and compatibility

The Transfer Port PA 30 is designed for BinTac platform air rifles in .22 calibre. It replaces the factory transfer port and integrates directly into the existing valve assembly without requiring additional adapters. Verify the original port dimensions of your specific BinTac model before installation to confirm fitment.

Maintenance and lifecycle

The adapter is serviceable and can be removed for inspection or cleaning during routine maintenance of the valve system. Check the port for debris or fouling whenever the action is disassembled to preserve consistent airflow.
