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

1. Depressurize the rifle completely
2. Unscrew the cylinder endcap from the action side
3. Remove the large o-ring from the endcap
4. Insert the Huma-Air regulator into the pressure tube with the pressure label facing the barrel
5. Reinstall the endcap

Bridge the factory regulator by removing its steel ball. Once removed, the original regulator becomes inactive and the Huma-Air unit controls pressure adjustment.
