Regulator Huma BSA SE
The Huma regulator regulates the air pressure in your BSA SE air rifle. The regulator reduces the primary high pressure to a lower pre-set pressure needed to get the pellet speed and improved accuracy you desire.
This regulator replaces the original "body adaptor" part of the air rifle. It's made of Chrome Molybdeen steel and has the same finish as the original BSA part.
It's very easy to install without having to drill holes or any other alterations. Please check the following link for the installation guide of this regulator: https://bit.ly/2KWxpKH and for the manual of how to adjust the regulator pressure you can check: https://bit.ly/2L6NaxA.
