** 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:

Once this cylinder with the APEX regulator is fitted you can fill to 250bar. The APEX Regulator is set to output a pressure above the standard regulator, allowing the standard regulator to work under less stress, often improving consistency and accuracy.

This item is compatible with the following air rifles:

HW100 KS & KT & BPK Models

Simply unscrew your standard cylinder assembly and replace it with ours. The air tube body is CNC machined from 6082T6 seamless aluminium, 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 as standard.

The main cylinder components are all CNC machined from 6082T6 aluminium and anodized black with a satin finish. 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. Our APEX Regulated cylinders have the valve removed so cannot be removed while pressurised like the OEM cylinder. Removal will cause the air to leak down until the cylinder is empty.

No quick fill 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.
