These complete lightweight cylinder assemblies are a direct replacement for the standard HW100 air rifle cylinder assembly. The lightweight cylinder is 50% lighter than the standard one. 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. The new quick fill end is fitted with a Rat Works pressure gauge (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.
For standard HW100 the maximum fill pressure is 200 bar the same as your standard cylinder. For HW100 fitted with a aftermarket regulator then you can fill safely to 250 bar. Fill a standard HW100 to 250 bar will result in performance issues.
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 o-ring 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 and fitting instructions.
