HW100 Lightweight Air Cylinder by Ratworks

RATWORKS HW100 air rifle compatible replacement air cylinder for HW100 Carbine, Rifle and FAC/Export models

These complete lightweight cylinder assemblies are a direct replacement for the standard HW100 air rifle cylinder assembly. The huge reduction in weight over the standard cylinder allows the rifle to be more balanced when shooting, and lighter when being carried around.

The cylinder components are all CNC machined from 6082T6 aluminium, the main body is made from seamless aluminium tube stock specially manufactured to our specification. The outer finish of the cylinder is anodized black with a satin finish. Fitted with an on-board Manometer (0-250bar) and have a built-in valve so they can be fitted and removed while pressurised. They use the standard HW100 fill probe to fill or can be filled using the MK1 HW100 Cylinder filling adaptor if desired.

Cylinder Specifications

The latest cylinders (May 2019 onwards) have a small amount more volume than the original so a small increase in shot count can be found. These cylinders are made to the same outer dimension as the standard tube, so no need to remove the oring in the front mounting. No quick fill plug is supplied or needed with this cylinder, as there is no chance of dirt ingress into the fill valve with our valve design, so no need for a dust plug. All cylinders are supplied with a full set of replacement seals.

Our RATWORKS cylinders have a maximum working pressure of 250bar and are safety pressure tested to 700bar. Be aware of imitation cylinders which have been known to fail when pressurised.

DO NOT EXCEED 200bar fill pressure with the standard HW100 regulator. 250bar fill is for RATWORKS Tench Regulated HW100 versions, or for cylinders fitted with Lancet regulators. Over filling when using the standard HW100 regulator will cause performance loss. 

Every tube is fully assembled and checked for leaks before dispatch. For UK buyers they are sent via 24hour courier, they are not sent pressurised. For international shipping the assemblies are disassembled and shipped disassembled.
