RAT Works HW100 Lightweight Complete Cylinder With Built In Regulator - Rifle (for HW100 S & T & BP Models)

The APEX Regulated HW100 lightweight cylinder is a direct replacement for the standard HW100 cylinder, allowing a 250bar fill for 50% more shots available with no modifications required.

Our APEX Regulated cylinders have the valve at the block end of the cylinder removed. Removal of the cylinder from the rifle under pressure will cause the air to leak down out of the regulator until the cylinder is empty.

Overall Complete Cylinder Length - 342mm

Cylinder Diameter - 37.1mm

** Top tip! - Measure from your breech block to the threads on your barrel, check the maximum length your rifle can accept without causing issues fitting a moderator/silencer. **

Fill Pressure:

This cylinder with the APEX regulator in can fill to 250bar. The APEX Regulator is set to output a pressure above the standard regulator, allowing it to work under less stress, often improving consistency and accuracy from your rifle.

This item is compatible with the following air rifles:

- Weihrauch HW100 (HW100 Sporter Thumbhole & BP Models)

The air tube body is CNC machined from 6082T6 seamless aluminium and anodized black with a satin finish, 50% lighter than the original stainless steel and 10% lighter than titanium. The volume of the air tube body is the same as the original air tube body, so there is no shot count increase if you do not fill above the original 200bar pressure of the HW100, but you may see an improvement in consistency if your regulator is causing variance in your rifle.

Our Quick Fill end is fitted with a RAT Works pressure gauge with a 0-300bar scale and uses your existing HW100 fill probe to fill.

No QF plug is supplied as standard or needed with our cylinder, as there is no chance of dirt ingress into the fill valve with our design, perfect for leak free, reliable shooting. If you’d like to add a plug for your own peace of mind, you can re-use your existing one, or purchase via the option below.

All cylinders are supplied with a full set of replacement seals and fitting instructions, please note, you will not be able to fill the cylinder off the rifle if you have the APEX regulator fitted.
