Huma-Air Tuning Regulator for Weihrauch HW100
This Huma-Air pressure regulator is engineered for the Weihrauch HW100 air rifle and installs directly into the pressure tube. Compatible with all HW1xx models featuring front fill or quick-fill units on the cylinder's front side.
The regulator vents to atmosphere without modifications to your pressure tube—no drilling required, eliminating power creep issues.
Installation Instructions
- Depressurize the rifle completely
- Unscrew the cylinder endcap from the action side
- Remove the large o-ring from the endcap
- Insert the Huma-Air regulator into the pressure tube with the pressure label facing the barrel
