Huben GK1 Regulator Huma Set

Regulator Conversion Kit Huma Huben GK1. Nice conversion kit so you can fit your unregulated GK1 with an internal adjustable regulator. Comes with regulator housing, New front with pressure gauge and fill probe. The pressure can be regulated from 70-160 bar. Huma advises to fill the gun after mounting this set with 300 bar Maximum.

This way you are guaranteed to shoot consistent speeds! The conversion is relatively simple. You replace the end cap on the reservoir, the center piece where the reservoir connects to and where you insert the fill plug in the standard version. Obviously bleed first before working on it. Pressure reservoirs are only safe when there is no pressure on them. Don't underestimate this!

About the youtube: Don't bleed like this with a high power version. Just use one of the bleeding screws (brass one under the plastic loading cap) or sliver one under the reservoir after you removed the trigger guard. Don't exhange springs on a high powered version. It makes the opening valve able to close.
