*** Now supplied in SILVER colour - NOT blue *** Z-Parts - HPA Adaptor Valve for KSC/KWA Gas Magazine - is a valve replacement for WE / KJW Green Gas Magazine, which allows the use of HPA rigs and systems with Airsoft Gas Blowback and None Blowback Pistols. The valve itself is CNC Machined from High Grade Aluminium and is anodized to give the valve extra protection from the elements. The valve is simple and easy to install, simply remove the original gas valve and replace it with the replacement! The valve can be removed easily, making it none-permanent, allowing you to convert your magazines back to Green Gas if required. This valve when used in conjunction with a HPA rig allows you to turn any of your KWC or KWA Style weapons into fully fledged HPA guns, giving you all the benefits associated with this. The benefits of this system are huge, such as no gas cool down, allowing you to fire as fast or as often as you want without the FPS dropping, as well as having a more consistent FPS. When used correctly this can turn an otherwise poor performing weapon on green gas into a the perfect weapon. This is perfect for any Airsoft Skirmisher who want to take their weapon to the next level, or be able to use their beloved weapon even during the coldest winter months.
