Huben K1 (2021-2025) Adjustable Tuning Regulator By Huma-Air

Externally adjustable Huma-Air tuning regulator for the Huben K1 airrifle made from 2021 up to current model 2025.

This adjustable tuning regulator, designed for the Huben K1, serves as a direct replacement for the original regulator. It helps enhance shot consistency and addresses common performance issues.

The compact design allows for increased regulated air volume, and installation is simple—just remove the factory regulator adapter and replace it with the new one, where the tuning regulator can be screwed in.

The regulator is vented to the atmosphere to prevent power creep over time. Pressure adjustments can be made externally, allowing for smooth and precise tuning. When decreasing pressure, adjustments should be made in small increments (about five clock minutes per step), with a shot fired after each adjustment to balance the pressure in the chamber.
